	* sem_ch7.adb (Install_Parent_Private_Declarations): When
	instantiating a child unit, do not install private declaration of
	a non-generic ancestor of the generic that is also an ancestor
	of the current unit: its private part will be installed when
	private part of ancestor itself is analyzed.

	* sem_ch12.adb (Instantiate_Object): In SPARK mode add a guard
	to verify that the actual is an object reference before checking
	for volatility.
	(Check_Generic_Child_Unit): Prevent cascaded errors when prefix
	is illegal.
