      Call Arity: In "e x", the result of "x" is not shared · a58eeb7f
      Joachim Breitner authored
      in contrast to "e (f x)", where CorePrep will turn it into "let y = f x
      in e x". So in
        let f = ...
        in e (f x)
      we know that f is called at most once, but in
        let f = ...
        in e f
      we do not know that.
      
      Previously Call Arity would assume that in "e x", "x" is evaluated at
      most once. This rarely would make a difference (the argument "x" is
      analized with an incoming arity of 0, so no eta-expansion would be done
      anyways), but of course this should still be fixed.
      
      This fixes #11064.
      
      Note the corresponding code dmdTransformThunkDmd in DmdAnal.
