(check_effective_target_c++11_only): New.
(check_effective_target_c++11_down): New.
(check_effective_target_c++1y): New.
(check_effective_target_c++1y_only): New.
(check_effective_target_c++98_only): Rename from

* class.c (type_has_user_declared_move_constructor): New.
(type_has_user_declared_move_assign): New.
(add_implicitly_declared_members): Add lazy copy ops
even if there's a move.
* method.c (lazily_declare_fn): Delete implicit copies
if there's a move.
(maybe_explain_implicit_delete): Explain this. Use inform rather
than error.
* cp-tree.h: Declare new fns.

gcc/cp/
* class.c (add_implicitly_declared_members): A class with no
explicitly declared copy or move constructor gets both declared
implicitly, and similarly for operator=.
(check_bases): A type with no copy ctor does not inhibit
a const copy ctor in a derived class.
(check_field_decl): Likewise.
(check_bases_and_members): A nonexistent copy ctor/op= is non-trivial.
* tree.c (type_has_nontrivial_copy_init): Adjust semantics.
(trivially_copyable_p): Likewise.
* call.c (convert_like_real): Use type_has_nontrivial_copy_init.
* class.c (finish_struct_bits): Likewise.
* tree.c (build_target_expr_with_type): Likewise.
* typeck2.c (store_init_value): Likewise.
libstdc++-v3/
* include/bits/unordered_map.h: Explicitly default copy constructors.
* include/bits/unordered_set.h: Likewise.

* call.c (build_over_call): Don't do bitwise copy for move ctor.
