This is a bogus approach and we knew it, we just were hoping to get
away with it.

I think a better approach is to register the ffi closure stubs
instead.  Those are unique per method and they'll let us get rid of
the linear search of interpreted stack frames.

I know Bryce was doing some work in this area recently, but I don't
know the status of it.
