[PATCH] D154953: [InstCombine] Remove the reminder loop if we know the mask is always true

[Robert Dazi via Phabricator via llvm-commits]

v01dXYZ added a comment.

I'm curious how such an optimisation is related to other passes such as ValueTracking or ScalarEvolution. Indeed, if we can use information about the op0 such as the LSBs or as a ScalarEvolutionValue, we could support non constant value.
