commands of the form
frame variable -f c-string foo
where foo is an arbitrary pointer (e.g. void*) now do the right thing, i.e. they deref the pointer and try to get a c-string at the pointed address instead of dumping the pointer bytes as a string. the old behavior is used as a fallback if things don’t go well

to in INADDR_LOOPBACK mode by default ("localhost only")
instead of INADDR_ANY ("accept connections from any system").
Add a new command line argument to debugserver, --open-connection
or -H which will enable the previous behavior. It would be used
if you were doing two-system debugging, with lldb running on one
system and debugserver running on the other. But it is a less
common workflow and should not be the default.

DWARFCallFrameInfo method which returns a RangeVector pre-size the
vector based on the number of entries it will be adding insted of
growing the vector as items are added.

- Added new abtract Results class to keep CoreFoundation out of the tests. There are many subclasses for different settings:
Results::Result::Dictionary
Results::Result::Array
Results::Result::Unsigned
Results::Result::Double
Results::Result::String
- Gauge<T> can now write themselves out via a templatized write to results function:
template <class T>
Results::ResultSP GetResult (const char *description, T value);
- There are four specializations of this so far:
template <>
Results::ResultSP GetResult (const char *description, double value);
template <>
Results::ResultSP GetResult (const char *description, uint64_t value);
template <>
Results::ResultSP GetResult (const char *description, std::string value);
template <>
Results::ResultSP GetResult (const char *description, MemoryStats value);
- Don't emit the virtual memory reading from the task info call as it really doesn't mean much as it includes way too much (shared cache + other stuff we don't have control over)
- Fixed other test cases to build correctly and use the new classes

Add a StopOthers method to AppleThreadPlanStepThroughObjCTrampoline, don't rely on the setting in the ThreadPlanToCallFunction, since that
gets pushed too late to determine which threads will continue.

Clang requires them to have complete types, but
we were previously only completing them if they
were of tag or Objective-C object types.
I have implemented a method on the ASTImporter
whose job is to complete a type. It handles not
only the cases mentioned above, but also array
and atomic types.

This returns a vector of <file address, size> entries for all of
the functions in the module that have an eh_frame FDE.
Update ObjectFileMachO to use the eh_frame FDE function addresses if
the LC_FUNCTION_STARTS section is missing, to fill in the start
addresses of any symbols that have been stripped from the binary.
Generally speaking, lldb works best if it knows the actual start
address of every function in a module - it's especially important
for unwinding, where lldb inspects the instructions in the prologue
of the function. In a stripped binary, it is deprived of this
information and it reduces the quality of our unwinds and saved
register retrieval.
Other ObjectFile users may want to use the function addresses from
DWARFCallFrameInfo to fill in any stripped symbols like ObjectFileMachO
does already.

This is especially useful to take measurements that span multiple test steps, or where you need to have different operations fall under the same measurement
An example of use is in the formatters perf test case

track the EH FDEs for the functions in a module to using a
RangeDataVector, a more light-weight data structure that only refers
to File addresses. Makes the initial FDE scan about 3x faster, uses
less memory.

of the data it writes down into the process even
if the process doesn't exist. This will allow
the IR interpreter to access static data allocated
on the expression's behalf.
Also cleaned up object ownership in the
IRExecutionUnit so that allocations are created
into the allocations vector. This avoids needless
data copies.

This test is incorrect as functions that return lldb.SBThread objects never return None, they just return lldb.SBThread objects that contain invalid opaque classes.

- TestCase.m_thread is now filled in with the first thread that has a valid
stop reason. This eliminates the need for the SelectMyThread() functions.
- The first thread that stops for a reason is also set as the selected thread
in the process in case any command line commands are run.
- Changed launch over to take a SBLaunchInfo parameter so that the launch
function doesn't keep getting new arguments as they are needed.
- TestCase::Setup() and TestCase::Launch(SBLaunchInfo) now return bool to
indicate success of setup and launch.
- ActionWanted::Next(SBThread) was renamed to ActionWanted::StepOver(SBThread)
- ActionWanted::Finish(SBThread) was renamed to ActionWanted::StepOut(SBThread)

Fixed a crasher in the SourceManager where it wasn't checking the m_target member variable for NULL.
In doing this fix, I hardened this class to have weak pointers to the debugger and target in case they do go away. I also changed SBSourceManager to hold onto weak pointers to the debugger and target so they don't keep objects alive by holding a strong reference to them.

and the JITted code are managed by a standalone
class that handles memory management itself.
I have removed RecordingMemoryManager and
ProcessDataAllocator, which filled similar roles
and had confusing ownership, with a common class
called IRExecutionUnit. The IRExecutionUnit
manages all allocations ever made for an expression
and frees them when it goes away. It also contains
the code generator and can vend the Module for an
expression to other clases.
The end goal here is to make the output of the
expression parser re-usable; that is, to avoid
re-parsing when re-parsing isn't necessary.
I've also cleaned up some code and used weak pointers
in more places. Please let me know if you see any
leaks; I checked myself as well but I might have
missed a case.

- don't use preprocessor macros
- use switch statements
- don't put anything in the lldb namespace, use "lldb_perf" namespace.
- Pass the action struct into each TestStep() for each step fill in
- Modify the ActionWanted class to have accessors to make the continue, next, finish, kill instead of using preproc macros
