2e722b915c Improve debugging information for BlockDeclRefExpr. WIP. Given this 
scheme, we can switch the previous scheme over to using this code
path.  There's a bit of simplifications yet to do as well.

9996138a80 Ok, an AssertingVH definitely doesn't work for now because we free our cache after the optimizer may have hacked on the module. Use a WeakVH instead.

f5c79709bc Update debug info generation for ObjCObjectPointer changes. 
- Previously this would crash on recursive types, and it was also incorrectly
   stripping off a level of indirection.
 - I'm not 100% convinced this is all correct, but it should be a monotonic
   improvment.

9fc4341eec It is possible that main input file does not have any symbol with debug info. To handle this edge case, always create main compile unit first. 
This fixes PR 4228.

a6acb390e7 Handle corner case where clang-cc is invoked directly to compile preprocessed source file without -main-file-name. In this case, CDDebugInfo is not able identify correct main source file becase SM.isFromMainFile() returns true for locations from header files as well as locations from main source file. 
This patch takes conservative approach by not emitting more then one compile unit with isMain bit set.

affb37337f reimplement debug info generation in terms of DebugInfo.h instead of 
using MachineModuleInfo.  This runs at about the same speed as the old
code, but fixes a bunch of bugs and is simpler and shorter.

607f67b16c Map compilation units using FileEntry pointers instead of 
FileIDs. This seems better conceptually and lets the SourceManager
handle details of mapping the location to a file ID.
 - In practice, fixes an assert because this code wasn't using
   getPhysicalLoc.

simplifies clients.

Also, add assert that RegionStack is empty when the CGDebugInfo is
destroyed.

b65ff27f53 A couple minor fixes to make debug info usable for arbitrary code: don't 
emit incomplete types, because they crash llc, and always use the 
logical location as the current location so we don't crash doing invalid 
queries on CurLoc.

1763075b9c Make debugging information usable. This is barebones, but it makes -g 
actually work (instead of crashing llc), and there's enough info emitted 
to get line number information in gdb. This should hopefully be helpful 
for debugging non-working programs.

I got rid of the begin/endregion calls because the implementation wasn't 
working; someone who knows the debugging info a bit better might try to 
add it. I really have no clue how a compiler is supposed to emit them.

This commit shouldn't have any effect without -g.

15cb669039 Added -g command line options to clang for generating source level debug information. This patch currently enables generation of line number debug information (stoppoints) and region begin/end debug information. The new files CGDebugInfo.h and CGDebugInfo.cpp implements the debug info manager class CGDebugInfo.
