[Ada] Remove End_Interp_List from the overloaded resolution API

gcc/ada/

	* sem_ch4.adb (Analyze_Call): Remove call to End_Interp_List.
	(Process_Overloaded_Indexed_Component): Remove call to
	End_Interp_List.
	* sem_util.adb (Insert_Explicit_Dereference): Remove call to
	End_Interp_List.
	* sem_type.ads (End_Interp_List): Remove.
	* sem_type.adb (Add_Entry): The guard against duplicate entries
	is now checked before other conditions, so that EXIT statements
	do not bypass this guard.
	(End_Interp_List): Remove.
