  * SpecConstr: Remove -fspec-inline-join-points, and add let-binding specialisation
  Ignore-this: afdc78550d4a20f0a41807970e2c9a8b
  
  The -fspec-inline-join-point thing was a gross hack intended to help
  Roman play around, but he's not using it and it was a terribly blunt
  instrument so I've nuked it.  
  
  Instead I've re-instated the let-binding specialiser. 
  See Note [Local let bindings]
