Write barrier elimination applies when there is no potential Dart call between a StoreFieldInstr and an AllocateObjectInstr. But the control flow between all potentially throwing instructions in a try block and the corresponding catch block is not explicitly repreresented in the flow graph, so the writer barrier elimination pass needs to handle catch entries specially.
