re PR libstdc++/37907 ([c++0x] support for std::is_standard_layout)
PR libstdc++/37907
Support std::is_standard_layout and std::is_trivial traits,
change POD to C++0x version (except for layout).
* gcc/c-common.c (c_common_reswords): Add __is_standard_layout
and __is_trivial.
* gcc/c-common.h (enum rid): Add RID_IS_STD_LAYOUT and RID_IS_TRIVIAL.
* gcc/cp/cp-tree.h (enum cp_trait_kind): Add CPTK_IS_STD_LAYOUT,
CPTK_IS_TRIVIAL.
(struct lang_type_class): Add non_std_layout.
(CLASSTYPE_NON_STD_LAYOUT): New.
* gcc/cp/class.c (check_bases): Set it.
(check_field_decls): Likewise.
(check_bases_and_members): Likewise.
* gcc/cp/parser.c (cp_parser_primary_expression): Handle RID_IS_STD_LAYOUT,
RID_IS_TRIVIAL.
(cp_parser_trait_expr): Likewise.
* gcc/cp/semantics.c (trait_expr_value): Handle CPTK_IS_STD_LAYOUT,
CPTK_IS_TRIVIAL.
(finish_trait_expr): Likewise.
* gcc/cp/tree.c (scalarish_type_p, trivial_type_p, std_layout_type_p): New.
(pod_type_p): Use them.
* gcc/cp/typeck.c (build_class_member_access_expr): Check
CLASSTYPE_NON_STD_LAYOUT rather than CLASSTYPE_NON_POD_P.
* libstdc++-v3/include/std/type_traits: Add is_standard_layout, is_trivial.
