using MachineModuleInfo.  This runs at about the same speed as the old
code, but fixes a bunch of bugs and is simpler and shorter.

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.

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

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.

Also take care of freeing memory at the right places.

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.

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.
