ada: Fix internal error with Put_Image aspect on access-to-class-wide type

This occurs with an instantiation of Ada.Containers.Vectors in a nested
package on an access-to-class-wide type declared with the Put_Image aspect
because of too late a freezing for the internal renaming generated for the
Put_Image procedure.

The change freezes this renaming immediately in this particular case; this
is similar to a trick used in Build_Array_Put_Image_Procedure.

gcc/ada/

	* sem_ch13.adb (New_Put_Image_Subprogram): In the nondeferred case
	coming from an aspect and for a type with delaying freezing, also
	freeze the subprogram immediately.
