This currently generates an IPC reply invocation like so:

    void SomeMessage::callReply(IPC::Decoder& decoder, CompletionHandler<void()>&& completionHandler)
    {
        completionHandler(WTFMove(*));
    }

I realized after posting this for review that I forgot to update the ChangeLog here after changing the bug title in Bugzilla. I'll fix the title before landing.
