	* exp_ch3.adb (Predefined_Primitive_Bodies): Generate the body of
	predefined primitive _Disp_Requeue.
	(Make_Predefined_Primitive_Specs): Create the spec for predefined
	primitive _Disp_Requeue.
	(Make_Predefined_Primitive_Specs/Predefined_Primitive_Bodies): Set the
	type of formal Renamed_Eq to Entity_Id (instead of Node_Id).
	(Make_Predefined_Primitive_Specs): Spec of "=" needed if the parent is
	an interface type. In case of limited interfaces we now declare all the
	predefined primitives associated with synchronized interfaces as
	abstract.
	(Predef_Spec_Or_Body): For interface types generate abstract subprogram
	declarations.
	(Predefined_Primitive_Bodies): Add body of "=" if the parent of the
	tagged type is an interface type and there is no user-defined equality
	function.
	Add also bodies of predefined primitives associated with synchronized
	interfaces.
	(Freeze_Record_Type): Do not build bodies of predefined primitives of
	interface types because they are now defined abstract.
	Add missing documentation.
	(Expand_Record_Controller): Update occurrence of Related_Interface
	to Related_Type.
	(Build_Offset_To_Top_Functions): Do nothing in case of VM.
	(Expand_N_Object_Declaration): Take into account VM_Target when handling
	class wide interface object declaration.
	(Expand_Previous_Access_Type): Do not create a duplicate master entity
	if the access type already has one.
	(Expand_N_Object_Declaration): Defend against attempt to validity check
	generic types. Noticed for -gnatVcf specified with previous errors.
