[JSC] Should not assume content in scratch register

rdar://problem/103201987
Reviewed by Justin Michaud.
We should not assume content in scratch register in MacroAssembler.
This patch fixes it so that X86 MacroAssembler functions correctly
set up content inside it.
We also fix naming of some X86 MacroAssembler functions since they
are not aligned to MacroAssembler's DEFINE_SIGNED_SIMD_FUNCS rules.
