of tagged extension types by not making field for components that are

(gnat_to_gnu_entity) <E_Record_Type>: Fix typo in the alignment formula
(gnat_to_gnu_entity) <E_Variable>: Do not convert again the
expression to the type of the object when the object is constant.
Reverse defer_debug_incomplete_list before traversing it, so that trees
are processed in the order at which they were added to the list. This
order is important when using the stabs debug format.
If we are deferring the output of debug information, also defer this
output for a function return type.
When adding fields to a record, prevent emitting debug information
for incomplete records, emit the information only when the record is
complete.
(components_to_record): New parameter defer_debug.
(gnat_to_gnu_entity, case E_Array_Subtype): Call copy_alias_set.

within a constrained subcomponent of an enclosing record, place the
freeze nodes in the scope stack entry for the enclosing record.
(Undelay_Type): New Subprogram.
(Set_Small_Size): Pass T, the type to modify; all callers changed.
(Freeze_Entity, Freeze_Record_Type): Change the way we handle types
within records; allow them to have freeze nodes if their base types
aren't frozen yet.
* sem_ch3.adb (Derived_Type_Declaration): New predicate
Comes_From_Generic, to recognize accurately that the parent type in a
derived type declaration can be traced back to a formal type, because
it is one or is derived from one, or because its completion is derived
from one.
(Constrain_Component_Type): If component comes from source and has no
explicit constraint, no need to constrain in in a subtype of the
enclosing record.

exp_attr.adb, exp_aggr.adb, exp_ch4.adb, exp_ch5.adb: Upgrade all the
uses of the Access_Disp_Table attribute to reference the first dispatch
table associated with a tagged type. As
part of the implementation of abstract interface types,
Access_Disp_Table has been redefined to contain a list of dispatch
tables (rather than a single dispatch table).
Similarly, upgrade all the references to Tag_Component by the
new attribute First_Tag_Component.

Clean up test in Expand_N_Object_Declaration for cases
where we need to do a separate assignment of the initial value.

additional tag assignment.

is to be deleted.
Bit packed array ops are only called if operands are known to be
aligned.
(Component_Equality): When returning an N_Raise_Program_Error statement,
ensure that its Etype is set to Empty to avoid confusing GIGI (which
expects that only expressions have a bona fide type).

(Set_Task_Body_Procedure): Removed.
These subprogram have been removed because the attribute
Task_Body_Procedure has been moved to the corresponding task type
or task subtype entity to leave a field free to store the list
of interfaces implemented by a task (for AI-345)
