There are a number of ways to get the value out of a rooted thing explicitly, but they differ depending on whether you have a Handle<> or a Root<>. Also, HeapPtr<> has its own method called get() to do pretty much the same thing. I like get() best because it's short, so I converted the other ones to it. I'm open to changing the name, but I think it's useful for them all to be the same.

Can the const method here just be removed?  It looks weird to have overloads that return either a T or a T&, and Rooted should never be const anyways.  (I see a CrossCompartmentKey constructor that does this, but that signature is broken)
