	* sem_type.adb (Add_One_Interp): If a candidate operation is an
	inherited interface operation that has an implementation, use the
	implementation to avoid spurious ambiguities.
	(Interface_Present_In_Ancestor): In case of concurrent types we can't
	use the Corresponding_Record_Typ attribute to look for the interface
	because it is set by the expander (and hence it is not always
	available). For this reason we traverse the list of interfaces
	(available in the parent of the concurrent type).
	(Interface_Present_In_Ancestor): Handle entities from the limited view
