* semantics.c (verify_constant): Track overflow separately.
(reduced_constant_expression_p): Don't check it here.
(cxx_eval_constant_expression): Check it on CSTs.
(cxx_eval_outermost_constant_expr): Treat overflows as non-constant
at this point, but still return the folded version.
(potential_constant_expression_1): Don't check overflow.
