Compute the sum of absolute differences of quadruplets of unsigned
8-bit integers in left and right, and store the 16-bit results
in right. Quadruplets are selected from left and right with
offsets specified in imm.

Each 128-bit chunk is treated independently (i.e., the value for
the is i-th 128-bit chunk of dest is calculated with the i-th
128-bit chunks of left and right).
