	* freeze.adb (Late_Freeze_Subprogram): Following AI05-151,
	a function can return a limited view of a type declared

	of the return type is available and the subprogram can now be
	frozen. However the freeze node cannot be inserted at the point
	of call, but rather must go in the package holding the function,
	so that the backend can process it in the proper context.
