Simon Pilgrim 39e5fc9030 [X86][SSE] Enable commutation between MOVHLPS and UNPCKHPD 
Assuming SSE2 is available then we can safely commute between these, removing some unnecessary register moves and improving memory folding opportunities.

VEX encoded versions don't benefit so I haven't added support to them.
