	* exp_ch5.adb, exp_pakd.adb, rtsfind.ads, freeze.adb, sem_util.adb,
	sem_util.ads, exp_aggr.adb
	(Exp_Aggr.Packed_Array_Aggregate_Handled): Simplify processing
	for reverse storage order aggregate.
	(Exp_Pakd.Byte_Swap): New utility routine used by...
	(Exp_Pakd.Expand_Bit_Packed_Element_Set,
	Expand_Packed_Element_Reference): For the case of a free-standing
	packed array with reverse storage order, perform byte swapping.
	(Rtsfind): Make new entities RE_Bswap_{16,32,64} available.
	(Freeze.Check_Component_Storage_Order): New utility routine
	to enforce legality rules for nested composite types whose
	enclosing composite has an explicitly defined Scalar_Storage_Order
	attribute.
	(Sem_Util.In_Reverse_Storage_Order_Object): Renamed from
	Sem_Util.In_Reverse_Storage_Order_Record, as SSO now applies to
	array types as well.
	(Exp_Ch5.Expand_Assign_Array): Remove now unnecessary kludge
	for change of scalar storage order in assignments. The Lhs and
	Rhs now always have the same scalar storage order.

	* sem_ch12.adb (Validate_Derived_Type_Instance): Handle properly
	the case of an instance of a child unit where a formal derived
	type DT is an extension of a type T declared in a parent unit,
	and the actual in the instance of the child is the type T declared
	in the parent instance, and that actual is not a derived type.
