Optimize fetching pixel values for SSE2 bilinear sampling
Most of the CPU time was spending in fetching pixel values instead of
calculating the bilinear sample. The access to vectors unions turns
out to be very slow, and should be avoided. This patch removes the
uses of vector,int array union in the bilinear sampling for SSE2.
