This seems like too complex and potentially problematic a transformation to
make in AutoUpgrade. We do similar transformations in
`convertNvvmIntrinsicToLlvm` which is called during InstCombine, but I think we
don't do this for "approx" intrinsics because the semantics don't match the
llvm versions.
