not get an "Unknown immediate size" assert failure when used. All instructions

Fixed the encoding problems of the crc32 instructions. All had the Operand size
...
override prefix and only the r/m16 forms should have had that. Also for variant
one, the AT&T syntax, added suffixes to all forms. Also added the missing
64-bit form for 'CRC32 r64, r/m8'. Plus added test cases for all forms and
tweaked one test case to add the needed suffixes.

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. :)

MC/Mach-O: Implement initial support for relaxation.
...
- The implementation is currently very brain dead and inefficient, but I have a
clear plan on how to fix it.
- The good news is, it works and correctly assembles 403.gcc (when built with
Clang, at '-Os', '-Os -g', and '-O3'). Even better, at '-Os' and '-Os -g',
the resulting binary is exactly equivalent to that when built with the system
assembler. So it probably works! :)
