  [InstCombine] Use KnownBits::urem() helper

This provides more precise results than the ad-hoc implementation.
Noticed while trying to add a consistency assertion.

To be honest I'm not sure why this code exists at all -- the
recursive calls are done with all bits demanded, so this should
be equivalent to just using the default case.
