    Define and use HsArg
    
    All this Left/Right business was making my head spin, so I defined
    
    data HsArg tm ty
      = HsValArg tm   -- Argument is an ordinary expression     (f arg)
      | HsTypeArg  ty -- Argument is a visible type application (f @ty)
    
    and used it.  This is just simple refactor; no change in behaviour.
