	given on a bad use of subtype predicate.
	* sem_ch5.adb (Analyze_Loop_Parameter_Specification): Enhance
	the error message given on a bad use of subtype predicate.
	* sem_util.adb (Bad_Predicated_Subtype_Use): Add formal parameter
	Suggest_Static. Emit an extra error message advising how to
	remedy the bad use of the predicate if the context warrants it.

	Suggest_Static along with a comment explaining its usage.

	* sem_disp.adb (Check_Dispatching_Operation): Further refinement
	to checks for AI05-0125: the check for a hidden primitive that
	may be overridden by the new declaration only applies if the
	hidden operation is never declared. This is not the case if the
	operation is declared in a parent unit.
