Hmm. That's a lot smaller than 128 bytes, right? I guess the point is
that you could't put _all_ of parent/first/last/next/prev/ownerdoc
inline, which is why they're all out of line?
What are type_id and abstract?
Will 'wrapper' go away in the long term for jsmanaged stuff?

Oh, and abstract is the current AbstractNode when inside of a
downcasting closure in the node hierarchy. It might be possible to
eliminate that now and simulate it via the wrapper instead.
