FYI: I posted a patch to implement the "manifestly constant evaluated" rule as https://reviews.llvm.org/D89360. It looks like the stricter rule doesn't work in practice; far too much C++ code uses `-frounding-math` and expects to be able to still include things like standard library headers that define `constexpr` functions and variables that involve floating-point rounding.
