Expand description

Sum the absolute differences of packed unsigned 8-bit integers.

Computes the absolute differences of packed unsigned 8-bit integers in `a` and `b`, then horizontally sum each consecutive 8 differences to produce two unsigned 16-bit integers, and pack these unsigned 16-bit integers in the low 16 bits of 64-bit elements returned.
