swrast/sse: Fix _mesa_sse_transform_pointsX_3d_no_rot
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. Now the correct commit instead of 66d09e4a2a6b770ddb which is not even close of correct fix for the bug.
