	* sem_ch3.adb (Add_Internal_Interface_Entities): Removing code that is
	no longer required after change in New_Overloaded_Entity.
	* sem_ch6.adb (New_Overloaded_Entity): Code reorganization to isolate
	the fragment of code that handles derivations of interface primitives.
	Add missing dependence on global variable Inside_Freezing_Actions to
	ensure the correct management of internal interface entities.
	* sem_ch13.adb (Analyze_Freeze_Entity): Add missing increase/decrease
	of the global variable Inside_Freezing_Actions to ensure that internal
	interface entities are well handled by New_Overloaded_Entity.
	* sem_disp.adb (Find_Primitive_Covering_Interface): Add documentation
	and complete the algorithm to catch hidden primitives derived of
	private type that covers the interface.
	* sem_disp.ads (Find_Primitive_Covering_Interface): Add missing
	documentation.
