* Re-implement the binder-swap stuff in OccurAnal
Ignore-this: 662ed559e161be958b1eff1a49d750a3
This is a pretty big patch, but it has a very local effect.
It affects only the binder-swap mechanism in OccurAnal, which
was not working well becuase it's more subtle than I'd realised
(See Note [getProxies is subtle]). I think this does a much
better job.
