Fix instruction encoding for XMM shifts with immediate count

 x86 keeps getting more and more devious: the source/dest operand
 is in the r/m field for these instructions, so REX.B must be set,
 rather than REX.R, to access > xmm7. Intel's new documentation
 seems clearer about these issues, at least.
