	* einfo.ads, einfo.adb (Access_Disp_Table_Elab_Flag): New
	attribute. Defined for record types and subtypes.
	* exp_ch3.ads (Init_Secondary_Tags): Adding new formal
	(Init_Tags_List) to facilitate generating separate code in the
	IP routine to initialize the object components and for completing
	the elaboration of dispatch tables.
	* exp_ch3.adb (Build_Init_Procedure): Improve the code
	generated in the IP routines by means of keeping separate
	the initialization of the object components from the
	initialization of its dispatch tables.	(Init_Secondary_Tags):
	Adding new formal (Init_Tags_List) and adjusting calls to
	Ada.Tags.Set_Dynamic_Offset_To_Top since it has a new formal;
	adjusting also calls to Ada.Tags.Register_Interface_Offset
	because the type of one of its formals has been changed.
	* a-tags.ads, a-tags.adb (Register_Interface_Offset): Profile
	modified. Instead of receiving a pointer to an object this
	routine receives now a primary tag.
	(Set_Dyanic_Offset_To_Top): Profile modified. This routine receives an
	additional formal: the tag of the primary dispatch table.
	* exp_disp.ads (Elab_Flag_Needed): New subprogram.
	* exp_disp.adb (Elab_Flag_Needed): New subprogram.
	(Make_Tags): Adding the declaration of the elaboration flag (if needed).

	formal in calls to Init_Secondary_Tags.
