ada: Better error message for bad Discard_Names configuration pragma

When a pragma Discard_Names is used as a configuration pragma, it does not
take an argument. If an argument is given, the resulting error message was
incorrect and confusing.

	* sem_prag.adb (Analyze_Pragma): Fix Is_Configuration_Pragma
	function to handle case where the pragma's parent is an
	N_Aspect_Specification node. In analyzing a Discard_Names pragma,
	do not assume that a nonzero number of arguments implies that the
	pragma is not a configuration pragma; that assumption only holds
	for legal programs.
