    Improve Core Lint, mainly for join points
    
    * lintSingleBinding: check that join points have
                         a valid join-point type
      (Trac #13281)
    
    * lintIdBinder: check that a JoinId is bound by
                    a non-top-level let
      i.e.  not a top level binder
            not lambda/case binder
    
    * Check for empty Rec [] bindings
    
    * Rename lintIdBndrs to lintLetBndrs
