	* sem_ch3.adb (Is_Visible_Component): Component is visible
	in a derived type if inherited through an ancestor that has a
	partial view of the original type holding the component, if the
	full view of that original type is in scope.
	* sem_util.ads (Get_Body_From_Stub): Works for all kinds of stubs.

	* sem_util.adb (Requires_Transient_Scope): For definite untagged
	subtypes, we should never have to use the secondary stack. This moves
	toward that goal. But there are still cases that don't work.
	Here, we move the check for Is_Definite first, but add a
	special-purpose check for Has_Discrim_Dep_Array.
