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

Variables view out of sync with lldb in Xcode is now fixed. Depending on what happened stack frames could get out of date and a stale shared pointer (one that is no longer a current frame in a thread) could end up being used. 

Now we don't store a weak_ptr to a frame in the ExecutionContextRef class, we just store its stack ID and we always regrab the frame from the thread by stack ID.

Performance improvements to the IsObjCNil () - we only try to resolve the value if the variable under consideration truly is an “Objective-C thing”
This also changes the ClangASTContext to make sure that id is correctly marked as being such an ObjC thing

resolved command, which it should not do.  It should adopt whatever context the
regular expression command was called with.  This was causing regular expression
commands run inside breakpoint commands to adopt the currently selected context,
not the one coming from the breakpoint that we hit.

lldb remembers not-found source file, setting target.source-map doesn't make it re-check for it. Now this is fixed. Each time the source path remappings get updated, the modification ID in the PathMappingList gets bumped and then we know the re-check for sources.

- fix TestCPPBool (was failing with some versions of GCC due to num_breakpoint_locations)
- speed up tests by skipping git/svn revision parsing by the test harness when running in lit-compatible (parsable) mode

Made the "--reverse" option to "source list" also be able to use the "--count". This helps us implement support for regexp source list command:

(lldb) l -10

Which gets turned into:

(lldb) source list --reverse --count 10

Also simplified the code that is used to track showing more source from the last file and line.
