	* exp_aggr.adb (Build_Record_Aggr_Code): Do not create master entity
	for task component, in the case of a limited aggregate. The enclosed
	object declaration will create it earlier. Otherwise, in the case of a
	nested aggregate, the object may appear in the wrong scope.
	(Convert_Aggr_In_Object_Decl): Create a transient scope when needed.
	(Gen_Assign): If the component being assigned is an array type and the
	expression is itself an aggregate, wrap the assignment in a block to
	force finalization actions on the temporary created for each row of the
	enclosing object.
	(Build_Record_Aggr_Code): Significant rewrite insuring that ctrl
	structures are initialized after all discriminants are set so that
	they can be accessed even when their offset is dynamic.
