does using an autoincrement and backing off on a match. As in the case of
the first code unit, using memchr() in the 8-bit library gives a big
speed up. Unlike the first_cu check above, we do not need to call
memchr() twice in the caseless case because we only need to check for the

The search can be skipped if the code unit was found later than the
current starting point in a previous iteration of the bumpalong loop.
