LGTM, see comments. @cfallin, any thoughts on a way to determine what SSE features are available during lowering?

X64Backend has a x64_flags field which contains this information, e.g. has_sse42() (as derived from the meta, x64 target-specific settings file); you could access it by changing slightly the signature of lower_insn_to_regs and passing it the self.x64_flags next to the self.flags.

Looks like it is already a parameter, it's just a matter of using it.
