Enabling support for the wchar_t type.
Without the proper language option setup, clang's ASTContexts will be configured to have wchar_t == int
This patch enables the correct options to make sure that we report wchar_t as itself

Enrico Granata b576bba229 <rdar://problem/12028723>
Adding useful formatting options to the expression (expr) command.
As a side effect of this change, the -d option now supports the same three-values enumeration that frame variables uses (run, don't run, none) instead of a boolean like it did previously

These options do not apply to print, p or po because these are aliased to not take any options.
In order to use them, use expression or expr.

Greg Clayton f9fc609fe7 Expanded the flags that can be set for a command object in lldb_private::CommandObject. This list of available flags are:
enum
{
    //----------------------------------------------------------------------
    // eFlagRequiresTarget
    //
    // Ensures a valid target is contained in m_exe_ctx prior to executing
    // the command. If a target doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidTargetDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidTargetDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresTarget         = (1u << 0),
    //----------------------------------------------------------------------
    // eFlagRequiresProcess
    //
    // Ensures a valid process is contained in m_exe_ctx prior to executing
    // the command. If a process doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidProcessDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidProcessDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresProcess        = (1u << 1),
    //----------------------------------------------------------------------
    // eFlagRequiresThread
    //
    // Ensures a valid thread is contained in m_exe_ctx prior to executing
    // the command. If a thread doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidThreadDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidThreadDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresThread         = (1u << 2),
    //----------------------------------------------------------------------
    // eFlagRequiresFrame
    //
    // Ensures a valid frame is contained in m_exe_ctx prior to executing
    // the command. If a frame doesn't exist or is invalid, the command
    // will fail and CommandObject::GetInvalidFrameDescription() will be
    // returned as the error. CommandObject subclasses can override the
    // virtual function for GetInvalidFrameDescription() to provide custom
    // strings when needed.
    //----------------------------------------------------------------------
    eFlagRequiresFrame          = (1u << 3),
    //----------------------------------------------------------------------
    // eFlagRequiresRegContext
    //
    // Ensures a valid register context (from the selected frame if there
    // is a frame in m_exe_ctx, or from the selected thread from m_exe_ctx)
    // is availble from m_exe_ctx prior to executing the command. If a
    // target doesn't exist or is invalid, the command will fail and
    // CommandObject::GetInvalidRegContextDescription() will be returned as
    // the error. CommandObject subclasses can override the virtual function
    // for GetInvalidRegContextDescription() to provide custom strings when
    // needed.
    //----------------------------------------------------------------------
    eFlagRequiresRegContext     = (1u << 4),
    //----------------------------------------------------------------------
    // eFlagTryTargetAPILock
    //
    // Attempts to acquire the target lock if a target is selected in the
    // command interpreter. If the command object fails to acquire the API
    // lock, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagTryTargetAPILock       = (1u << 5),
    //----------------------------------------------------------------------
    // eFlagProcessMustBeLaunched
    //
    // Verifies that there is a launched process in m_exe_ctx, if there
    // isn't, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagProcessMustBeLaunched  = (1u << 6),
    //----------------------------------------------------------------------
    // eFlagProcessMustBePaused
    //
    // Verifies that there is a paused process in m_exe_ctx, if there
    // isn't, the command will fail with an appropriate error message.
    //----------------------------------------------------------------------
    eFlagProcessMustBePaused    = (1u << 7)
};

Now each command object contains a "ExecutionContext m_exe_ctx;" member variable that gets initialized prior to running the command. The validity of the target objects in m_exe_ctx are checked to ensure that any target/process/thread/frame/reg context that are required are valid prior to executing the command. Each command object also contains a Mutex::Locker m_api_locker which gets used if eFlagTryTargetAPILock is set. This centralizes a lot of checking code that was previously and inconsistently implemented across many commands.

Python OS plug-ins now fetch thread registers lazily.

Also changed SBCommandInterpreter::HandleCommand() to not take the API lock. The logic here is that from the command line you can execute a command that might result in another thread (like the private process thread) to execute python or run any code that can re-enter the public API. When this happens, a deadlock immediately occurs for things like "process launch" and "process attach".

Add unconditional logging messages to every place in debugserver
where we send a SIGKILL signal or do a ptrace PT_KILL call to
terminate the inferior process.  When the debuggee is silently
killed off, the console logging from debugserver can disambiguate
whether debugserver killed off the process because it failed to
completely set it up, becuase it was told to (via the "k" packet),
or if some external daemon killed it.

Implement the ability for Python commands to be interrupted by pressing CTRL+C
Also add a new Mutex subclass that attempts to be helpful for debugging by logging actions performed on it

FYI of all interested - there is a separate deadlocking issue related to how LLDB dispatches CTRL+C that might cause LLDB to deadlock upon pressing CTRL+C while in a Python command.
This is not a regression, and was just previously masked by us not even trying to bail out of Python commands, so that it would not be clear from a user perspective whether we were
deadlocked or stuck in an inconsistent state within the Python interpreter.

Sean Callanan 7be70e8528 This patch removes the SymbolFileSymtab support
for reporting class types from Objective-C runtime
class symbols.  Instead, LLDB now queries the 
Objective-C runtime for class types.

We have also added a (minimal) Objective-C runtime
type vendor for Objective-C runtime version 1, to 
prevent regressions when calling class methods in
the V1 runtime.

Other components of this fix include:

- We search the Objective-C runtime in a few more
  places.

- We enable enumeration of all members of
  Objective-C classes, which Clang does in certain
  circumstances.

- SBTarget::FindFirstType and SBTarget::FindTypes
  now query the Objective-C runtime as needed.

- I fixed several test cases.

Update the debugserver "qProcessInfo" implementation to return the
cpu type, cpu subtype, OS and vendor information just like qHostInfo
does so lldb can create an ArchSpec based on the returned values.

Add a new GetProcessArchitecture to GDBRemoteCommunicationClient akin
to GetHostArchitecture.  If the qProcessInfo packet is supported,
GetProcessArchitecture will return the cpu type / subtype of the 
process -- e.g. a 32-bit user process running on a 64-bit x86_64 Mac
system.

Jim Ingham c627682ef7 Fixed a few bugs in the "step in" thread plan logic.
Added a "step-in-target" flag to "thread step-in" so if you have something like:

Process 28464 stopped
* thread #1: tid = 0x1c03, function: main , stop reason = breakpoint 1.1
    frame #0: 0x0000000100000e08 a.out`main at main.c:62
   61         
-> 62         int A6 = complex (a(4), b(5), c(6)); // Stop here to step targetting b and hitting breakpoint.
   63             

and you want to get into "complex" skipping a, b and c, you can do:

(lldb) step -t complex
Process 28464 stopped
* thread #1: tid = 0x1c03, function: complex , stop reason = step in
    frame #0: 0x0000000100000d0d a.out`complex at main.c:44
   41     
   42     int complex (int first, int second, int third)
   43     {
-> 44         return first + second + third;  // Step in targetting complex should stop here

Enrico Granata 7b8c513f08 Option changes:
the option to print the runtime-specific description has been modified in the frame variable, memory read and expression command.

All three commands now support a --object-description option, with a shortcut of -O (uppercase letter o)

This is a breaking change:
frame variable used --objc as the long option name
expression used -o as a shortcut
memory read uses --objd as the long option name

Hopefully, most users won't be affected by the change since people tend to access "expression --object-description" under the alias "po" which still works

The test suite has been tweaked accordingly.

Sean Callanan 496970f6ee Fixed the IRInterpreter's handling of "this" and
"self" when those pointers are in registers.
Previously in this case the IRInterpreter would
handle them just as if the user had typed in
"$rdi", which isn't safe because $rdi is passed
in through the argument struct.

Now we correctly break out all three cases (i.e.,
normal variables in registers, $reg, and this/self),
and handle them in a way that's a little bit easier
to read and change.

This results in more accurate printing of "this" and
"self" pointers all around.  I have strengthened the
optimized-code test case for Objective-C to ensure
that we catch regressions in this area reliably in
the future.

The problem was that InferiorCallMmap was not setting its ThreadPlanCallFunction to private and so the completion of that thread plan appeared to be the stop reason and therefore the 'continue' operation failed to step over the breakpoint. The SetPrivate call is being put in ThreadPlanCallFunction rather than InferiorCallMmap to make the solution more general.

I modified the "Args::StringtoAddress(...)" function to be able to evaluate address expressions. This is now used for any command line arguments or options that takes addresses like:

memory read <addr> [<end-addr>]
memory write <addr>
breakpoint set --address <addr>
disassemble --start-address <addr> --end-address <addr>

It calls the expression parser to evaluate the address expression and will also work around the issue where the compiler doesn't like to add offsets to function pointers (which is what happens when you try to evaluate "main + 12"). So there is a temp fix in the Args::StringtoAddress() to work around this until we can get special compiler support for debug expressions with function pointers.

Fixed zero sized arrays to work correctly. This will only happen once we get a clang that emits correct debug info for zero sized arrays. For now I have marked the TestStructTypes.py as an expected failure.

Sean Callanan eab6cc98d7 The expression parser will now check the validity
of the "self"/"this" pointer for the current stack
frame before wrapping expressions in C++ or
Objective-C methods.  This works around bad debug
info where the compiler emits a "this" or "self"
but doesn't give any way to find its location.

Sean Callanan faa0bb3fa1 Rewrote the bitfield logic. Major changes include:
- Removed the BitfieldMap class because it is unnecessary.
  We now just track the most recently added field.

- Moved the code that calculates bitfield widths so it
  can also be used to determine whether it's necessary
  to insert anonymous fields.

- Simplified the anonymous field calculation code into
  three cases (two of which are resolved identically).

- Beefed up the bitfield testcase.
