	* exp_ch9.ads, exp_ch9.adb (Build_Protected_Entry,
	Build_Unprotected_Subprogram_Body): Generate debug info for
	declarations related to the handling of private data in task and
	protected types.
	(Debug_Private_Data_Declarations): New subprogram.
	(Install_Private_Data_Declarations): Remove all debug info flagging.
	This is now done by Debug_Private_Data_Declarations at the correct
	stage of expansion.
	(Build_Simple_Entry_Call): If the task name is a function call, expand
	the prefix into an object declaration, and make the surrounding block a
	task master.
	(Build_Master_Entity): An internal block is a master if it wraps a call.
	Code reformatting, update comments. Code clean up.
	(Make_Task_Create_Call): Use 'Unrestricted_Access instead of 'Address.
	(Replicate_Entry_Formals): If the formal is an access parameter or
	anonymous access to subprogram, copy the original tree to create new
	entities for the formals of the subprogram.
	(Expand_N_Task_Type_Declaration): Create a Relative_Deadline variable
	for tasks to store the value passed using pragma Relative_Deadline.
	(Make_Task_Create_Call): Add the Relative_Deadline argument to the
	run-time call to create a task.
	(Build_Wrapper_Spec): If the controlling argument of the interface
	operation is an access parameter with a non-null indicator, use the
	non-null indicator on the wrapper.

	* sem_ch9.adb (Analyze_Protected_Type): Only retrieve the full view when
	present, which it may not be in the case where the type entity is an
	incomplete view brought in by a limited with.
	(Analyze_Task_Type): Only retrieve the full view when present, which it
	may not be in the case where the type entity is an incomplete view
	brought in by a limited with.
	(Analyze_Protected_Definition): Set Is_Frozen on all itypes generated for
	private components of a protected type, to prevent the generation of
	freeze nodes for which there is no proper scope of elaboration.

	* exp_util.ads, exp_util.adb (Remove_Side_Effects): If the expression is
	a function call that returns a task, expand into a declaration to invoke
	the build_in_place machinery.
	(Find_Protection_Object): New routine.
	(Remove_Side_Effects): Also make a copy of the value
	for attributes whose result is of an elementary type.
	(Silly_Boolean_Array_Not_Test): New procedure
	(Silly_Boolean_Array_Xor_Test): New procedure
	(Is_Volatile_Reference): New function
	(Remove_Side_Effects): Use Is_Volatile_Reference
	(Possible_Bit_Aligned_Component): Handle slice case properly

	* exp_pakd.adb (Expand_Packed_Not): Move silly true/true or false/false
	case test to Exp_Util
	(Expand_Packed_Xor): Move silly true/true case test to Exp_Util
