	* sem_disp.adb (Check_Dispatching_Operation): Do not flag subprograms
	inherited from an interface ancestor by another interface in the
	context of an instance as 'late'.
	(Is_Tag_Indeterminate, Propagate_Tag): Handle properly the dereference
	of a call to a function that dispatches on access result.
	(Check_Dispatching_Operation): In case of late overriding of a primitive
	that covers abstract interface subprograms we register it in all the
	secondary dispatch tables associated with abstract interfaces.
	(Check_Dispatching_Call): Add check that a dispatching call is not made
	to a function with a controlling result of a limited type. This is a
	current implementation restriction.
	(Check_Controlling_Formal): Remove bogus checks for E.2.2(14).
	(Check_Dispatching_Operation): Do no emit a warning if the controlling
	argument is an interface type that is a generic formal.
	(Is_Interface_Subprogram): Removed.
	(Check_Dispatching_Operation): If the subprogram is not a dispatching
	operation, check the formals to handle the case in which it is
	associated with an abstract interface type.
