Add support for macho relocations. (#378)

Browse Source 
This requires splitting X86PCRel4 into two separate relocations, to
distinguish the case where the instruction is a call, as Mach-O uses a
different relocation in that case.

This also makes it explicit that only x86-64 relocations are supported
currently.
