f16c12d7a1 MC/Mach-O: Remove some FIXMEs.

2493ddfe42 MC/Mach-O/x86_64: Darwin's special "signed_N" relocation types should only be 
used to replace a normal relocation, not a reference to a GOT entry.

53ce0e12d8 MC/Mach-O/x86_64: Fix PCrel adjustment for x86_64, which was using the fixup 
offset instead of the fixup address as intended.

7c6f0e3827 MC/Mach-O: As Kevin pointed out, 'Address' is really an offset -- rename to clarify.

75778984f9 MC/Mach-O: Fix another mismatch with .weak_definition, we shouldn't use a 
scattered relocation entry with a .weak_definition.

51bed9c870 Fix i386 relocations to Weak Definitions. The relocation entries should be 
external and the item to be relocated should not have the address of the
symbol added in.

f3a53baf00 MC/Mach-O: Mark absolute variable's appropriately, and add Mach-O support for 
writing them.

a0ab4bf989 MC: Change MCObjectWriter::RecordRelocation to take an MCFragment (instead of a MCDataFragment). Object files should only need the generic MCFragment features.

1a81ad3559 MC/Mach-O/x86_64: Add relocation support. 
- This is "extraordinarily" Darwin 'as' compatible. See the litany of FIXMEs littered about for more information.
 - There are a few cases which seem to clearly be 'as' bugs which I have left unsupported, and there is one cases where we diverge but should fix if it blocks diffing .o files (Darwin 'as' ends up widening a jump unnecessarily).
 - 403.gcc build, runs, and diffs equivalently to the 'as' built version now (using llvm-mc). However, it builds so slowly that I wouldn't recommend trying it quite yet. :)
