Now that we have RTTI in userspace, we can do away with all this manual hackery and use dynamic_cast. We keep the is<T> and downcast<T> helpers since they still provide good readability improvements. Note that unlike dynamic_cast<T>, downcast<T> does not fail in a recoverable way, but will assert if the object being casted is not a T.
