	* exp_atag.adb, exp_atags.ads
	(Build_Common_Dispatching_Select_Statement): Replace argument DT_Ptr

	Ada.Tags has not been previously loaded.

	Build_VM_TSDs if package Ada.Tags has not been previously loaded.
	* sem_aux.adb
	(Enclosing_Dynamic_Scope): Add missing support to handle the full
	view of enclosing scopes. Required to handle enclosing scopes that
	are synchronized types whose full view is a task type.

	analyzing lists with empty nodes.
	(Make_Disp_Asynchronous_Select_Body): Add support for VM targets.
	(Make_Disp_Conditional_Select_Body): Add support for VM targets.
	(Make_Disp_Get_Prim_Op_Kind): Add support for VM targets.

	of objects (object declaration and parameter specification), with
	appropriate locations and units, for use in local cross-references.
	(Generate_Reference): update fields Sub, Slc and Sun. Keep newly created
	references of type 'I' for initialization in object definition.

	Write_Entity_Name outside of the body. Ignore references of types 'D'
	and 'I' introduced for local cross-references.

	cross-references sections.
	(Lref_Entity_Status): new array defining whether an entity is a local
