	* exp_util.adb (Find_Interface_ADT): Retrieve Designated_Type instead of
	Directly_Designated_Type when the type argument is an access type.
	(Find_Interface_Tag): Retrieve Designated_Type instead of
	Directly_Designated_Type when the type argument is an access type.
	(Has_Controlled_Coextensions): Retrieve Designated_Type instead of
	Directly_Designated_Type of each access discriminant.
	* sem_res.adb (Resolve_Type_Conversion): Retrieve Designated_Type
	instead of Directly_Designated_Type when the operand and target types
	are access types.

	* exp_aggr.adb (Flatten): Return False if one choice is statically
	known to be out of bounds.
