llvmpipe: fix arguments order given to vec_andc
This patch fixes a classic "confuse the enemy" bug.
_mm_andnot_si128 (SSE) and vec_andc (VMX) do the same operation, but the
arguments are opposite.
_mm_andnot_si128 performs "r = (~a) & b" while
vec_andc performs "r = a & (~b)"
To make sure this error won't return in another place, I added a wrapper
function, vec_andnot_si128, in u_pwr8.h, which makes the swap inside.
