This procedure does not insert a call for raising the exception because

* atree.adb: Minor reformatting
* exp_ch3.adb (Expand_Derived_Record): Rename to
Expand_Record_Extension.
(Build_Record_Init_Proc.Build_Assignment): The default expression in
a component declaration must remain attached at that point in the
tree so New_Copy_Tree copies it if the enclosing record type is derived.
It is therefore necessary to take a copy of the expression when building
the corresponding assignment statement in the init proc.
As a side effect, in the case of a derived record type, we now see the
original expression, without any rewriting that could have occurred
during expansion of the ancestor type's init proc, and we do not need
to go back to Original_Node.
* exp_ch3.ads (Expand_Derived_Record): Rename to
Expand_Record_Extension.
* exp_dist.ads, exp_dist.adb (Underlying_RACW_Type): New subprogram.

New subprograms. Used to create a proxy tagged object for a remote
subprogram. The proxy object is used as the designated object
for RAS values on the same partition (unless All_Calls_Remote applies).
(Build_Get_Unique_RP_Call): New subprogram. Build a call to
System.Partition_Interface.Get_Unique_Remote_Pointer.
(Add_RAS_Access_TSS, Add_RAS_Dereference_TSS):
Renamed from Add_RAS_*_Attribute.
(Add_Receiving_Stubs_To_Declarations): Generate a table of local
subprograms.
New implementation of expansion for remote access-to-subprogram types,
based on the RACW infrastructure.
* exp_dist.ads (Copy_Specification): Update comment to note that this
function can copy the specification from either a subprogram
specification or an access-to-subprogram type definition.

* sem_type.adb (Disambiguate): Handle properly an accidental ambiguity
in an instance, between an explicit subprogram an one inherited from a

* exp_ch6.adb (Expand_N_Subprogram_Body): If polling is enabled, do not
add a polling call if the subprogram is to be inlined by the back-end,
to avoid repeated calls with multiple inlinings.
* checks.adb (Apply_Alignment_Check): If the expression in the address
clause is a call whose name is not a static entity (e.g. a dispatching
call), treat as dynamic.
