I kind of hope this makes sense.

(Preliminary result is that it avoids regressions in test/CodeGen/VE/Scalar/max.ll and test/CodeGen/AArch64/fast-isel-select.ll, when looking adding it on top of https://github.com/llvm/llvm-project/pull/84924 . So maybe not ground breaking when it comes to reducing amount of test case diffs for that patch.)
