Are we going to need this thread override?  If all you want is to get messages
on the main thread you can just inherit from IPC::Listener and call
OnMessageReceived in the render_thread_impl.cc.  (Or it'd be probably ok to just
add IPC_MESSAGE_HANDLER() case for CreateWorker msg directly in the
render_thread_impl.cc-- if the reviewer agrees)

I deleted EmbeddedSharedWorkerMessageFilter from this CL.

EmbeddedSharedWorkerStub will be created when CreateWorker message is received
by RenderThreadImpl. 

+  virtual bool OnMessageReceived(const IPC::Message& msg) OVERRIDE;
+
+  scoped_refptr<base::MessageLoopProxy> main_thread_loop_proxy_;
+
+  DISALLOW_COPY_AND_ASSIGN(EmbeddedSharedWorkerMessageFilter);
+};
+
+}  // namespace content

+#endif  // CONTENT_RENDERER_SHARED_WORKER_EMBEDDED_SHARED_WORKER_MESSAGE_FILTER_H_
