We can't reuse the result due to the different value of mce; the first time we
have mce_unknown, the second time mce_true. The first time is for possible
warnings in cp_build_binary_op; perhaps we should lower the max constexpr
iteration count for such speculative folding?
Relatedly, cp_b_b_o should probably use fold_for_warn instead of cp_fully_fold.
