	* call.c (standard_conversion): instantiate_type here.
	(reference_binding): And here.
	(implicit_conversion): Not here.
	(build_op_delete_call): No need to cons up an OVERLOAD.

	* typeck.c (decay_conversion): Take the address of overloaded
	functions, too.
	(require_instantiated_type): Lose.
	(convert_arguments): Don't handle unknown types here.
	(build_c_cast): Likewise.
