    M llvm/test/Transforms/InstSimplify/fminmax-folds.ll
    M llvm/test/Transforms/InstSimplify/fp-nan.ll

  Log Message:
  -----------
  [InstSimplify] try harder to propagate existing NaN values through FP folds

Any undef element in a vector would trigger the whole constant
to be replaced with a canonical NaN. This propagates each
element when possible.
