(Transmit_As_Unconstrained): New function.
(Build_Ordered_Parameters_List): Use the above to order parameters.
(GARLIC_Support.Build_General_Calling_Stubs):
Use the above to determine which parameters to unmarshall using 'Input

* 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

* 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

* exp_ch7.adb (Find_Final_List): Change the test for generating a
selected component from an access type's Associated_Final_Chain to
check for the presence of that field, rather than assuming it exists
for all named access types.
(Make_Clean): New formal Chained_Cleanup_Action allowing to specify a
procedure to call at the end of the generated cleanup procedure.
(Expand_Cleanup_Actions): When a new cleanup procedure is generated, and
and an At_End_Proc already exists in the handled sequence of statements
