Computes the sum of absolute differences (SADs) of quadruplets of unsigned
8-bit integers in a compared to those in b, and stores the 16-bit
results in dst. Eight SADs are performed for each 128-bit lane using one
quadruplet from b and eight quadruplets from a. One quadruplet is
selected from b starting at on the offset specified in imm8. Eight
quadruplets are formed from sequential 8-bit integers selected from a
starting at the offset specified in imm8.
