	* exp_ch3.ads, exp_ch3.adb (Analyze_N_Full_Type_Declaration): For an
	anonymous access component, do not create a master_id if type already
	has one, as may happen if the type is a subcomponent of a packed array
	type.
	(Build_Init_Procedure, Component_Needs_Simple_Initialization,
	Initialize_Tag): Remove code associated with the old CPP pragmas.
	CPP_Virtual and CPP_Vtable are no longer supported.
	(Build_Offset_To_Top_Internal): Add support for concurrent record types
	(Build_Offset_To_Top_Functions): Add support for concurrent record types
	(Freeze_Record_Type): Remove call to
	Init_Predefined_Interface_Primitives.
	(Init_Secondary_Tags.Initialize_Tag): New subprogram containing all the
	code required to initialize the tags of the secondary dispatch tables.
	This leaves the algoritm more clear.
	(Init_Secondary_Tags): Add support for concurrent record types
	(Make_Predefined_Primitive_Specs): Code cleanup.
	(Predefined_Primitive_Bodies): Code cleanup.
	(Build_Master_Renaming): New local subprogram.
	(Expand_N_Full_Type_Declaration): Build the master_id associated with
	anonymous access to task type components.
	(Expand_N_Subtype_Indication): The bounds of a range constraint in a
	subtype indication are resolved during analysis, and must not be done
	here.
	(Stream_Operation_OK): Check Restriction_Active before RTE_Available.
