	* exp_aggr.adb (Build_Record_Aggr_Code): For extension aggregates, if
	the parent part is a build-in-place function call, generate assignments.
	(Expand_Record_Aggregate): Call Convert_To_Assignments if any components
	are build-in-place function calls.
	(Replace_Self_Reference): New subsidiary of
	Make_OK_Assignment_Statement, to replace an access attribute that is a
	self-reference into an access to the appropriate component of the
	target object. Generalizes previous mechanism to handle self-references
	nested at any level.
	(Is_Self_Referential_Init): Remove, not needed.
	(Is_Self_Referential_Init): New predicate to simplify handling of self
	referential components in record aggregates.
	(Has_Default_Init_Comps, Make_OK_Assignment_Statement): Add guard to
	check for presence of entity before checking for self-reference.
	(Has_Default_Init_Comps): Return True if a component association is a
	self-reference to the enclosing type, which can only come from a
	default initialization.
	(Make_OK_Assignment_Statement): If the expression is of the form
	Typ'Acc, where Acc is an access attribute, the expression comes from a
	default initialized self-referential component.
	(Build_Record_Aggr_Code): If the type of the aggregate is a tagged type
	that has been derived from several abstract interfaces we must also
	initialize the tags of the secondary dispatch tables.
