	* einfo.ads, einfo.adb (Has_Predicates): Flag is now on all entities
	(simplifies code).
	* exp_ch13.adb (Build_Predicate_Function): Output info msgs for
	inheritance.
	* sem_ch13.adb (Analyze_Aspect_Specifications): Make sure we have a
	freeze node for entities for which a predicate is specified.
	(Analyze_Aspect_Specifications): Avoid duplicate calls
	* sem_ch3.adb (Analyze_Full_Type_Declaration): Remove attempt to avoid
	duplicate calls to Analye_Aspect_Specifications.

	* a-exextr.adb, atree.ads, freeze.adb: Minor reformatting.
