PR middle-end/37005
* fold-const.c (maybe_canonicalize_comparison_1): Require
undefined overflow only for canonicalizing A +- CST cmp CST.
Make sure to not generate new constants that are not inside
their TYPE_MIN/MAX_VALUE range.
(maybe_canonicalize_comparison): Remove undefined overflow
checking from here.
(fold_binary): Remove now duplicate folding.
