cb4ed696ef Re-re-enable compact unwind after fixing a failure in SingleSource/Benchmarks/Shootout-C++/except.cpp and friends. It was encoding the stored registers in the wrong order.

28140f744a Relocation against a symbol, instead of against section. We had some extreme 
test cases where there were a lot of relocations applied relative to a large
rodata section. Gas would create a symbol for each of these whereas we would
be relative to the beginning of the rodata section. This change mimics what
gas does.

b72534060e LLVMBuild: Introduce a common section which currently has a list of the 
subdirectories to traverse into.
 - Originally I wanted to avoid this and just autoscan, but this has one key
   flaw in that new subdirectories can not automatically trigger a rerun of the
   llvm-build tool. This is particularly a pain when switching back and forth
   between trees where one has added a subdirectory, as the dependencies will
   tend to be wrong. This will also eliminates FIXME implicitly.

b5c511f7b7 Handle reloc_signed_4byte in here. Not doing so was a regression from my 
previous commit. It is strange that we see it in 32 bits. We already
have a fixme about it.

63cf89d532 The second part of support for generating dwarf for assembly source files. This 
generates the dwarf Compile Unit DIE and a dwarf subprogram DIE for each
non-temporary label.

The next part will be to get the clang driver to enable this when assembling
a .s file.  rdar://9275556

82e22767cf Handle the case of the magical _GLOBAL_OFFSET_TABLE_ showing up in a 
symbol difference. This matches gas behavior and fixes PR11513.

We still don't handle _GLOBAL_OFFSET_TABLE_ in data sections.

2f57374e32 Darwin assembler improved relocs when w/o subsections_via_symbols. 
When the file isn't being built with subsections-via-symbols, symbol
differences involving non-local symbols can be resolved more aggressively.
Needed for gas compatibility.

633ce3426c Move target-specific logic out of generic MCAssembler. 
Whether a fixup needs relaxation for the associated instruction is a
target-specific function, as the FIXME indicated. Create a hook for that
and use it.

5fade79478 MC/X86/COFF: Allow quotes in names when targeting MS/Windows, 
as MC is the only assembler we support.

This splits MS/Windows and GNU/Windows ASM infos into two seperate classes.
While there is currently only one difference, full MS C++ ABI support will
require many more.

a52be4ff03 Clients are responsible for initializing the targets, remove it from the disassembler API. 
This will break users of the LLVMCreateDisasm API (not that I know of any). They have to call the 
LLVMInitializeAll* functions from llvm-c/Target.h themselves now. edis' C API in all its horribleness 
should be unaffected.
