Wrong code emited for psrlw xmm, imm

[Edouard Gomez]

Test case:
section .text
foobar:
    psrlw xmm0, 1 ; assembled to 66 0f d1 d0 01 instead of 66 0f 71 d0 01
    psrld xmm0, 1 ; assembled to 66 0f d2 d0 01 instead of 66 0f 72 d0 01
    psrlq xmm0, 1 ; assembled to 66 0f d3 d0 01 instead of 66 0f 73 d0 01

The mmx versions are fine, i suspect a typo somewhere in x86id.re as it
assembles this code to the psrl?? xmm, xmm version.
