f3840d2c16 Add in the first iteration of support for llvm/clang/lldb to allow variable per address space pointer sizes to be optimized correctly.

6a7efcfc02 Always use the string pool, even when it makes the .o larger. This may help 
tools that read the debug info in the .o files by making the DIE sizes more
consistent.

345ef343cc DwarfDebug: Allocate DIEValues with a BumpPtrAllocator. Most of them are 
POD-like anyway, so we don't even care about calling their d'tors (DIEBlock
being the exception).

57578766aa simplify EmitSectionOffset to always use .set if it is 
available, the only thing this affects is that we produce
.set in one case we didn't before, which shouldn't harm
anything.  Make EmitSectionOffset call EmitDifference
instead of duplicating it.

6f01d9c2f0 There is no need to use FoldingSet to unique DIEs. 
DIEs are created from MDNode, which are already uniqued. And DwarfDebug already uses ValueMaps to find and use existing DIE for a given MDNode.

c23197a26f llvm_unreachable->llvm_unreachable(0), LLVM_UNREACHABLE->llvm_unreachable. 
This adds location info for all llvm_unreachable calls (which is a macro now) in
!NDEBUG builds.
In NDEBUG builds location info and the message is off (it only prints
"UREACHABLE executed").

c25e7581b9 assert(0) -> LLVM_UNREACHABLE. 
Make llvm_unreachable take an optional string, thus moving the cerr<< out of
line.
LLVM_UNREACHABLE is now a simple wrapper that makes the message go away for
NDEBUG builds.

88423eecd0 Split out the Dwarf writer stuff into separate files. This is a much more 
logical/sane approach to organizing all of the stuff that goes into writing out
DWARF information. Honestly? even this is too complex for what it's supposed to
be doing.

Trivia: It *looks* like there would be functionality changes, however there aren't!
