Well, OK, partially wrong. The undef question needs to be answered, yes. But what we really need is to hook into the constant folding that we're reaching via foldOrCommuteConstant() but are currently avoiding except in the default FP environment. That'll take longer to fix, but D102673 <https://reviews.llvm.org/D102673> is a step in the right direction.
