Re-distribute hierarchical vector match pattern
Re-distribute hierarchical vector match pattern

This commit modifies the hierarchical vector match patter. It
avoids repeated SAD computation at same points. The function
vp9_vector_sad_sse2 is called 12 times per 64x64 block, instead
of 15 times as before. The effective coverage remains the same.
