140; This version of CHECK2 has 3 fewer instructions on sets older than SSE4 but I
141; am not sure whether it is any faster. A rewrite or refactor of the filter
142; code should make it possible to eliminate the move instruction at the end. It
143; exists to satisfy the expectation that the "score" values are in m1.
