re PR c/86125 (missing -Wbuiltin-declaration-mismatch on a mismatched return type)

	PR c/86125
	* c-decl.c (last_fileptr_type): Remove.
	(last_structptr_types): New variable.
	(match_builtin_function_types): Compare TYPE_MAIN_VARIANT of
	{old,new}rettype instead of the types themselves.  Assert
	last_structptr_types array has the same number of elements
	as builtin_structptr_types array.  Use TYPE_MAIN_VARIANT for
	argument oldtype and newtype.  Instead of handling
	just fileptr_type_node specially, handle all builtin_structptr_types
	pointer nodes.  Formatting fix.

	* c-common.c (c_common_nodes_and_builtins): Build type variants for
	builtin_structptr_types types even for C.

	* gcc.dg/Wbuiltin-declaration-mismatch-7.c: Guard testcase for
	lp64, ilp32 and llp64 only.
	(fputs): Use unsigned long long instead of size_t for return type.
	(vfprintf, vfscanf): Accept arbitrary target specific type for
	va_list.
