	* sem_ch12.adb (Insert_Freeze_Node_For_Instance):  Further
	refinements on the placement of a freeze node for a package
	instantiation, when the generic appears within a previous
	instantiation in the same unit.If the current instance is within
	the one that contains the generic, the freeze node for the
	current one must appear in the current declarative part. Ditto
	if the current instance is within another package instance. In
	these cases the freeze node of the previous instance is is not
	relevant. New predicate Enclosing_Body simplifies the process.

	Enclosing_Package_Body, to prevent confusion with subprogram of
