I have now duplicated all the relevant tests into InstCombine and added comments that these no longer fold as part of InstSimplify. The only test I've dropped outright is the assume.ll one, as I don't think it makes sense if we don't perform top-level KnownBits folding. I've left the remaining ones alone, but could drop them if desired.
