The only interesting test change is in @PR31262, where the following fold is now performed, while it previously was not: https://alive2.llvm.org/ce/z/a5Qmr6 llvm/test/Transforms/InstSimplify/ConstProp/gep.ll has not been updated, because there is a tradeoff between folding and inrange preservation there that we may want to discuss. Updates have been performed using: https://gist.github.com/nikic/98357b71fd67756b0f064c9517b62a34
