	* sem_ch3.ads, sem_ch3.adb (Check_Abstract_Overriding): Avoid
	generation of spurious error if parent is an interface type; caused
	because predefined primitive bodies will be generated later by
	Freeze_Record_Type.
	(Process_Subtype): The subtype inherits the Known_To_Have_Preelab_Init
	flag.
	(Derive_Subprograms): Handle derivations of predefined primitives
	after all the user-defined primitives to ensure that they are
	found in proper order in instantiations.
	(Add_Interface_Tag_Components, Inherit_Components): Update occurrences
	of Related_Interface to Related_Type.
	(Record_Type_Declaration): Minor reordering of calls to decorate the
	Tag component because the entity must have set its Ekind attribute
	before setting its Is_Tag attribute.
	(Analyze_Subtype_Declaration): In the case of subtypes with
	Private_Kind, inherit Known_To_Have_Preelab_Init from the parent.
