4841121580 Add an empty key for DebugLoc so that you can store an empty DebugLoc in a
DenseMap.

84e679beea rename NewDebugLoc -> DebugLoc, prune #includes in DebugLoc.h.
This keeps around temporary typedef for clang/llvm-gcc so the
build won't break when I commit this :)

175edf2c78 fix a bug in DebugRecVH::deleted/allUsesReplacedWith. If an
entry in the Scope+InlinedAt drops to a non-canonical form,
we need to reset the idx member of both VH's to 0.

68c5513499 add a method to decode a DILocation into a NewDebugLoc.

b227925fa3 Add a new "NewDebugLoc" class which will eventually replace DebugLoc,
and will replace the 'DbgInfo' member in Instruction.

The benefit of NewDebugLoc is that it is compact (8 bytes vs 12/24 
bytes for the DbgInfo member in Instruction on a 32/64 bit system),
it means that we will end up not having to allocate MDNodes to 
represent the "DILocations" in common cases of -O0 -g, and it is
much more efficient to get things out of than the MDNode.
