tcg: Add atomic128 helpers
Force the use of cmpxchg16b on x86_64. Wikipedia suggests that only very old AMD64 (circa 2004) did not have this instruction. Further, it's required by Windows 8 so no new cpus will ever omit it. If we truely care about these, then we could check this at startup time and then avoid executing paths that use it. Reviewed-by: Emilio G.
