Noah Goldstein	8a60814ed5	[ValueTracking] Use KnownBits functions for computeKnownBits of saturating add/sub functions ... The knownbits implementation covers all the cases previously handled by `uadd.sat`/`usub.sat` as well some additional ones. We previously were not handling the `ssub.sat`/`sadd.sat` cases at all.
