Yes, XORPS = SSE1, PXOR = MMX if used on mm[0..7] and SSE2 if used on
xmm[0..7]

PXOR user in code were causing the lowest SP float register to have NaN
values which made all math operations in that slot fail. Correct istruction
to clear float registers is XORPS which handles single precission floats
correctly.
Fixes progs/tests/fog in swrast SSE mode.
