	* sem_ch3.adb (Complete_Private_Subtype): If the full view is a task
	or protected type with discriminants, do not constrain the
	corresponding record type if the subtype declaration has no
	discriminant constraints. This can be the case in source code, or in
	the subtype declaration created to rename an actual type within an
	instantiation.
