Greg Clayton dd36defda7 Added a new Host call to find LLDB related paths:
static bool
    Host::GetLLDBPath (lldb::PathType path_type, FileSpec &file_spec);
    
This will fill in "file_spec" with an appropriate path that is appropriate
for the current Host OS. MacOSX will return paths within the LLDB.framework,
and other unixes will return the paths they want. The current PathType
enums are:

typedef enum PathType
{
    ePathTypeLLDBShlibDir,          // The directory where the lldb.so (unix) or LLDB mach-o file in LLDB.framework (MacOSX) exists
    ePathTypeSupportExecutableDir,  // Find LLDB support executable directory (debugserver, etc)
    ePathTypeHeaderDir,             // Find LLDB header file directory
    ePathTypePythonDir              // Find Python modules (PYTHONPATH) directory
} PathType;

All places that were finding executables are and python paths are now updated
to use this Host call.

Added another new host call to launch the inferior in a terminal. This ability
will be very host specific and doesn't need to be supported on all systems.
MacOSX currently will create a new .command file and tell Terminal.app to open
the .command file. It also uses the new "darwin-debug" app which is a small
app that uses posix to exec (no fork) and stop at the entry point of the 
program. The GDB remote plug-in is almost able launch a process and attach to
it, it currently will spawn the process, but it won't attach to it just yet.
This will let LLDB not have to share the terminal with another process and a
new terminal window will pop up when you launch. This won't get hooked up
until we work out all of the kinks. The new Host function is:

    static lldb::pid_t
    Host::LaunchInNewTerminal (
        const char **argv,   // argv[0] is executable
        const char **envp,
        const ArchSpec *arch_spec,
        bool stop_at_entry,
        bool disable_aslr);

Cleaned up FileSpec::GetPath to not use strncpy() as it was always zero 
filling the entire path buffer.

Fixed an issue with the dynamic checker function where I missed a '$' prefix
that should have been added.

Greg Clayton d59cea2d23 prefix more stuff with '$' to make sure we don't go trying to lookup anything
we don't need to.

Greg Clayton 7b462cc18a Made many ConstString functions inlined in the header file.
Changed all of our synthesized "___clang" functions, types and variables
that get used in expressions over to have a prefix of "$_lldb". Now when we
do name lookups we can easily switch off of the first '$' character to know
if we should look through only our internal (when first char is '$') stuff,
or when we should look through program variables, functions and types.

Converted all of the clang expression code over to using "const ConstString&" 
values for names instead of "const char *" since there were many places that
were converting the "const char *" names into ConstString names and them
throwing them away. We now avoid making a lot of ConstString conversions and
benefit from the quick comparisons in a few extra spots.

Converted a lot of code from LLVM coding conventions into LLDB coding 
conventions.

Sean Callanan e2ef6e380b Updated to latest LLVM. Major LLVM changes:
- Sema is now exported (and there was much rejoicing.)

 - Storage classes are now centrally defined.

Also fixed some bugs that the new LLVM picked up.

Sean Callanan 9e6ed53ea5 Bugfixes to the expression parser. Fixes include:
- If you put a semicolon at the end of an expression,
   this no longer causes the expression parser to
   error out.  This was a two-part fix: first,
   ClangExpressionDeclMap::Materialize now handles
   an empty struct (such as when there is no return
   value); second, ASTResultSynthesizer walks backward
   from the end of the ASTs until it reaches something
   that's not a NullStmt.

 - ClangExpressionVariable now properly byte-swaps when
   printing itself.

 - ClangUtilityFunction now cleans up after itself when
   it's done compiling itself.

 - Utility functions can now use external functions just
   like user expressions.

 - If you end your expression with a statement that does
   not return a value, the expression now runs correctly
   anyway.

Also, added the beginnings of an Objective-C object
validator function, which is neither installed nor used
as yet.

Sean Callanan afa4237d9b Fixed an expression parser bug that prevented
certain functions from being resolved correctly.

Some functions (particularly varargs functions)
are BitCast before being called, and the problem
was that a CallInst where getCalledValue()
returned a BitCast ConstantExpr was not being
relocated at all.

This problem should now be resolved for the case
of BitCast.

Sean Callanan 8e999e4015 Added code to run pointer validation checks in
expressions.  If an expression dereferences an
invalid pointer, there will still be a crash -
just now the crash will be in the function
___clang_valid_pointer_check().

Sean Callanan 6961e87847 Added support for dynamic sanity checking in
expressions.  Values used by the expression are
checked by validation functions which cause the
program to crash if the values are unsafe.

Major changes:

- Added IRDynamicChecks.[ch], which contains the
  core code related to this feature

- Modified CommandObjectExpression to install the
  validator functions into the target process.

- Added an accessor to Process that gets/sets the
  helper functions
