ada: Storage_Error on Ordered_Maps container aggregate with enumeration Key_Type

The compiler fails with a Storage_Error when compiling a container aggregate
for a Map type coming from an instantiation of Ada.Containers.Ordered_Maps
that specifies an enumeration type for the Key_Type formal.

gcc/ada/ChangeLog:

	* exp_aggr.adb (Build_Container_Aggr_Code.To_Int): Apply Enumeration_Pos
	to Entity (Expr) rather than Expr.
