	* 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.
