	DR 1351
	Represent the unevaluated exception specification of an implicitly
	declared or deleted function with a simple placeholder, not a list
	of functions.
	* cp-tree.h (UNEVALUATED_NOEXCEPT_SPEC_P): New.
	* except.c (unevaluated_noexcept_spec): New.
	* class.c (deduce_noexcept_on_destructor): Use it.
	* decl.c (check_redeclaration_exception_specification): Call
	maybe_instantiate_noexcept.
	(duplicate_decls): Call it before merge_types.
	(start_preparsed_function): Call maybe_instantiate_noexcept.
	* decl2.c (mark_used): Call maybe_instantiate_noexcept earlier.
	* init.c (get_nsdmi): Factor out of perform_member_init.
	* method.c (process_subob_fn): Call maybe_instantiate_noexcept.
	(walk_field_subobs): Consider NSDMI for EH spec.
	(get_defaulted_eh_spec): New.
	(implicitly_declare_fn): Use unevaluated_noexcept_spec.
	(defaulted_late_check): Defer EH checking in non-template classes.
	(after_nsdmi_defaulted_late_checks): New.
	* parser.c (cp_parser_class_specifier_1): Use it.
	(unparsed_classes): New macro.
	* parser.h (cp_unparsed_functions_entry_d): Add classes field.
	* pt.c (maybe_instantiate_noexcept): Use get_defaulted_eh_spec.
	Remove list-of-functions handling.
	* typeck2.c (merge_exception_specifiers): Remove list-of-functions
	handling and FN parameter.
	* typeck.c (merge_types): Adjust.
