* aspects.adb, aspects.ads: Add Aspect_Abstract_State to all the
relevant tables.
* einfo.ads, einfo.adb: Add Integrity_Level and Refined_State to
the description of fields (Abstract_States): New routine.
(Integrity_Level): New routine.
(Has_Property): New routine.
(Is_Input_State): New routine.
(Is_Null_State): New routine.
(Is_Output_State): New routine.
(Is_Volatile_State): New routine.
(Refined_State): New routine.
(Set_Abstract_States): New routine.
(Set_Integrity_Level): New routine.
(Set_Refined_State): New routine.
(Write_Field8_Name): Add proper output for E_Abstract_State.
(Write_Field9_Name): Add proper output for E_Abstract_State.
(Write_Field25_Name): Add proper output for E_Package.
* lib-xref.ads: Add new letter for an abstract state.
* par-prag.adb: Add pragma Abstract_State to the list of pragma
that do not need special processing by the parser.
* sem_ch13.adb (Analyze_Aspect_Specifications): Convert
aspect Abstract_State into a pragma without any form
of legality checks. The work is done by Analyze_Pragma.
(Check_Aspect_At_Freeze_Point): Aspect Abstract_State does not
require delayed analysis.
* sem_prag.adb: Add a value for pragma Abstract_State in table
Sig_Flags.
(Analyze_Pragma): Add legality checks for pragma
Abstract_State. Analysis of individual states introduces a state
abstraction entity into the visibility chain.
* snames.ads-tmpl: Add new names for abstract state and
integrity. Add new pragma id for abstract state.

* table.adb (Reallocate): Calculate new Length in
Long_Integer to avoid overflow.

* sem_ch3.adb, sinfo.ads, freeze.adb, sem_ch4.adb, exp_aggr.adb
(Sem_Ch3.Analyze_Object_Declaration): Set Ekind early so that
it is set properly when expanding the initialization expression.
(Freeze.Check_Address_Clause): Transfer initialization expression
to an assignment in the freeze actions, so that the object is
initialized only after being elaborated by GIGI.
(Sinfo (comments), Sem_Ch4.Analyze_Expression_With_Actions): Allow
a Null_Statement as the expression in an Expression_With_Actions.
(Exp_Aggr.Collect_Initialization_Statements): New subprogram
shared by expansion of record and array aggregates, used to
capture statements for an aggregate used to initalize an object
into an Expression_With_Actions (which acts as a container for
a list of actions).
(Exp_Aggr.Convert_Aggr_In_Obj_Decl): Use the above to
capture initialization statements, instead of the previously
existing loop which left freeze nodes out of the capturing
construct (causing out of order elaboration crashes in GIGI).
(Exp_Aggr.Expand_Array_Aggregate): Use the above to capture
initialization statements (this was previously not done for
arrays). Also do not unconditionally prevent in place expansion
for an object with address clause.
