Jason Merrill ac1774315c Machinery to support implicit delete/move. 
* cp-tree.h: (struct lang_type_class): Add lazy_move_assign,
	has_complex_move_ctor, has_complex_move_assign bitfields.
	(CLASSTYPE_LAZY_MOVE_ASSIGN): New.
	(TYPE_HAS_COMPLEX_MOVE_ASSIGN): New.
	(TYPE_HAS_COMPLEX_MOVE_CTOR): New.
	(enum special_function_kind): Add sfk_move_assignment.
	(LOOKUP_SPECULATIVE): New.
	* call.c (build_over_call): Return early if it's set.
	(build_over_call): Use trivial_fn_p.
	* class.c (check_bases): If the base has no default constructor,
	the derived one is non-trivial.  Handle move ctor/op=.
	(check_field_decl): Likewise.
	(check_bases_and_members): Handle move ctor/op=.
	(add_implicitly_declared_members): Handle CLASSTYPE_LAZY_MOVE_ASSIGN.
	(type_has_move_constructor, type_has_move_assign): New.
	* decl.c (grok_special_member_properties): Handle move ctor/op=.
	* method.c (type_has_trivial_fn, type_set_nontrivial_flag): New.
	(trivial_fn_p): New.
	(do_build_copy_constructor): Use it.
	(do_build_assign_ref): Likewise.  Handle move assignment.
	(build_stub_type, build_stub_object, locate_fn_flags): New.
	(locate_ctor): Use locate_fn_flags.
	(locate_copy, locate_dtor): Remove.
	(get_dtor, get_default_ctor, get_copy_ctor, get_copy_assign): New.
	(process_subob_fn, synthesized_method_walk): New.
	(maybe_explain_implicit_delete): New.
	(implicitly_declare_fn): Use synthesized_method_walk,
	type_has_trivial_fn, and type_set_nontrivial_flag.
	(defaulted_late_check): Set DECL_DELETED_FN.
	(defaultable_fn_check): Handle sfk_move_assignment.
	(lazily_declare_fn): Clear CLASSTYPE_LAZY_* early.  Don't declare
	implicitly deleted move ctor/op=.
	* search.c (lookup_fnfields_1): Handle sfk_move_assignment.
	(lookup_fnfields_slot): New.
	* semantics.c (omp_clause_info_fndecl): Remove.
	(cxx_omp_create_clause_info): Use get_default_ctor, get_copy_ctor,
	get_copy_assign, trivial_fn_p.
	(trait_expr_value): Adjust call to locate_ctor.
	* tree.c (special_function_p): Handle sfk_move_assignment.
