This client looks nice -- it inherits from both
NoBaseWillBeGarbageCollectedFinalized and HeapSupplement. It would be consistent
if all clients follow the rule :)

I've followed the alternative rule: place the GC base at the left-most outermost
position that is actually allocatable. The intermediates are really interfaces
and can remain mixins.

-    static PassOwnPtr<WorkerPermissionClient> create(PassOwnPtr<WebWorkerPermissionClientProxy>);

     virtual ~WorkerPermissionClient();
