[X86] Strengthen some of the SD type constraints in X86InstrFragmentsSIMD.td

This effects the vector shift and rotates as well as some of the vector compares.

The changes to the shifts by immediates allows a few hundred bytes to be removed by removing type checks for the size of the immediate containing the shift/rotate amount.
