Okay, I just checked the CanonicalizeFreezeInLoops tests, and there is one case that it handles but InstCombine doesn't: https://github.com/llvm/llvm-project/blob/c6b88cb9184fc6c17bb3d9c2c9568646dc46638d/llvm/test/Transforms/CanonicalizeFreezeInLoops/onephi.ll#L361 This is the case where the step value needs to be frozen.
