This checkin removes the last Cocoa formatters that were implemented in Python and reimplements them in C++. The Python Cocoa formatters are not shipped as part of LLDB anymore, but still exist in the source repository for user reference. Python formatters still exist for STL classes and users can still define their own Python formatters

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.

When built with cmake, only call the string functions when the previous commands (utils/GetSourceVersion & utils/GetRepositoryPath successed). Otherwise, they fail when not launched from a repository

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 Depending on what happened stack frames could get out of date and a stale shared pointer (one that is no longer a current frame in a thread) could end up being used.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

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.

Add a target setting (target.use-fast-stepping) to control using the "run to next branch" stepping algorithm.

llvm-svn: 176958

The step by running from branch to branch pretty much works with this checkin (at least for x86_64) but is still
turned off, it needs more qualification.  If you want to play with it, change the initialization of m_use_fast_step
to true.

Don't use the fact that we stopped with a "Breakpoint" stop reason to decide to step over the breakpoint.  It's

Drop the old f registers from debugserver's register list.  Add the
NEON 128-bit q registers to debugserver, support reading and writing.
Add the new contains / invalidates mappings for the s, d, and q 
registers so lldb will know what registers overlay what other registers.
Change the default format of s and d registers to be floating point
instead of hex.  Remove some UTF-8 hyphen chars in comments in the ARM
register number definition headers.
