	* sem_ch8.ads, sem_ch8.adb (Find_Type, case of a 'Base attribute
	reference): Use correct entity as denoted entity for the selector of
	the rewritten node.
	(Find_Direct_Name): Add comment about Generate_Reference incorrectly
	setting the Referenced_As_LHS flag for entities that are implicitly
	dereferenced.
	(Find_Type): If the type is an internally generated incomplete type,
	mark the full view as referenced, to prevent spurious warnings.
	(Find_Selected_Component, Has_Components): Handle properly non-limited
	views that are themselves incomplete types.
	Handle interfaces visible through limited-with clauses.
	(Analyze_Subprogram_Renaming): Disambiguate and set the entity of a
	subprogram generic actual for which we have generated a renaming.
	Warn when the renaming introduces a homonym of
	the renamed entity, and the renamed entity is directly visible.
