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. :) git-svn-id: https://llvm.org/svn/llvm-project/llvm/trunk@98974 91177308-0d34-0410-b5e6-96231b3b80d8
