[X86] Teach X86InstrInfo::commuteInstructionImpl to use MOVSD/MOVSS for BLEND under optsize when the immediate allows it.
Isel currently emits movss/movsd a lot of the time and an accidental double commute turns it into a blend.
Ideally we'd select blend directly in isel under optspeed and not rely on the double commute to create blend.
