v01dXYZ added a comment to D154953: [InstSimplify] Remove the remainder loop if we know the mask is always true.

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.
