This allows the implementation to be defined per architecture. Specifically this addresses the fact that x86-64 MacroAssembler implements far calls as a load to register, followed by a call to register. Patching the call actually requires the pointer load to be patched, rather than the call to be patched. This is implementation detail specific to MacroAssemblerX86_64, and as such is best handled there.
