<pre class="commit-message" style="white-space: pre-wrap; margin: 0;">Work in progress on runRW#

This is a proof of concept, in progress. It treats

    runRW# (\s. e)

specially in three ways

* In the simplifier, we transform

    K[ runRW# rr ty (\s. body) ]

    -->  runRW rr' ty' (\s. K[ body ])

  where K is a context

* In Lint, join points are allowed to occur inside the continuation.

    join j x = rhs

    in runRW# (\s. case ... of

                     A -> j 1

                     B -> ...

                     C -> J 2)

  Very much as they can occur in other join points.

* In OccurAnal, we infer join points using the same rule

We get much beter optimisation as a result.

Still not finished.  E.g. Float out may take

    runST# (\s. e)

and float that lambda out.  But really we want to keep

that lambda in runST#'s argument, otherwise things that

were join point might stop being so.

But it's a start
