Craig Topper e753247b06 [X86] Add PS<->PD domain changing support for MOVH/MOVL load instructions and MOVH store instructions. ...

These instructions don't have an integer domain equivalent, but
we can at least change between the two floating point domains.

This allows a smaller encoding on SSE targets if we can turn
PD into PS.
