  1. alloc: Implement downcast Rc<Any> -> Rc<T> 

    Implement downcast the like it exists for Box.

The implementation avoids using into_raw/from_raw, because the pointer
arithmetic which should cancel does not seem to optimize out at the
moment.

Since Rc<T> is never Send, only Rc<Any> and not Rc<Any + Send>
implements downcast.
