re PR translation/90035 (Non-translatable C++ parser diagnostics)

	PR translation/90035
	* parser.h (struct cp_parser): Add
	type_definition_forbidden_message_arg member.
	* parser.c (cp_debug_parser): Print it.
	(cp_parser_check_type_definition): Pass
	parser->type_definition_forbidden_message_arg as second argument to
	error.
	(cp_parser_has_attribute_expression, cp_parser_sizeof_operand): Set
	parser->type_definition_forbidden_message_arg and use G_() with
	%qs for parser->type_definition_forbidden_message instead of
	building untranslatable message using concat.
