Log message:
	* c-common.c (c_format_attribute_table): Make format and
	format_arg attributes apply to function types rather than to
	decls.
	(is_valid_printf_arglist): Construct an attribute list and pass
	that to check_function_format rather than a name.
	* c-common.h (check_function_format): Adjust prototype.
	* c-decl.c (duplicate_decls): Preserve attributes from type of
	built-in decl when allowing for harmless conflict in types.
	* c-format.c (record_function_format,
	record_international_format, function_format_list,
	international_format_info, international_format_list): Remove.
	(function_format_info): Remove next, name and assembler_name.
	Make format_num and first_arg_num be unsigned HOST_WIDE_INT.
	(decode_format_attr): New.
	(handle_format_attribute): Handle receiving a type rather than a
	decl.  Call decode_format_attr.  Store format information in a
	function_format_info.
	(handle_format_arg_attribute): Correct comment.  Handle receiving
	a type rather than a decl.  Use unsigned HOST_WIDE_INT for
	arg_num.
	(check_format_info_recurse, check_format_info_main): Take argument
	numbers as unsigned HOST_WIDE_INT.
	(check_function_format): Take a list of attributes from the
	function type rather than a name or assembler name.  Check for
	format attributes in that list and the attributes on the type of
	the current function rather than looking through
	function_format_list.
	(check_format_info): Use unsigned HOST_WIDE_INT for argument
	numbers.
	(check_format_info_recurse): Take format_arg attributes from the
	type of the function calls rather than using
	international_format_list.  Allow for multiple format_arg
	attributes.
	* c-typeck.c (build_function_call): Pass type attributes to
	check_function_format rather than name or assembler name.  Don't
	require there to be a name or assembler name to check formats.
	
	cp:
	* call.c (build_over_call), typeck.c (build_function_call_real):
	Pass type attributes to check_function_format rather than name or
	assembler name.  Don't require there to be a name or assembler
	name to check formats.
	
	testsuite:
	* g++.dg/warn/format2.C, gcc.dg/format/attr-7.c,
	gcc.dg/format/multattr-1.c, gcc.dg/format/multattr-2.c,
	gcc.dg/format/multattr-3.c: New tests.
	* gcc.dg/format/attr-3.c: Update expected error texts.  Remove
	tests for format attributes on function pointers being rejected.
