    Some cleanup of the Exitification code
    
    based on a thorough review by Simon in comments
    https://ghc.haskell.org/trac/ghc/ticket/14152#comment:33
    through 37.
    
    The changes are:
    
     * `isExitJoinId` is moved to `SimplUtils`, because
       it is only valid when occurrence information is up-to-date.
     * Abstracted variables are properly sorted using `sortQuantVars`
     * Exitification does not set occ info.
    
     And then minor quibles to notes and avoiding some unhelpful shadowing
     of local names.
