Correct conversion/overflow behavior.
* cvt.c (ignore_overflows): Move here from typeck.c.
(ocp_convert): Use it.
(cp_fold_convert): Use it. Don't call rvalue.
* typeck.c (build_static_cast_1): Don't use it. Do call rvalue.
* error.c (location_of): Handle expressions, too.
* class.c (check_bitfield_decl): Set input_location around call to
cxx_constant_value.
* semantics.c (cxx_eval_outermost_constant_expr): Don't
print the expression if it already had TREE_OVERFLOW set.
(reduced_constant_expression_p): Check TREE_OVERFLOW_P for C++98, too.
(verify_constant): Allow overflow with a permerror if we're
enforcing.
(cxx_eval_outermost_constant_expr): Use verify_constant.
(adjust_temp_type): Use cp_fold_convert.
* decl.c (build_enumerator): Don't call constant_expression_warning.
* decl2.c (grokbitfield): Likewise.
