  * Add absentError.  
  
  This patch accompanies the HEAD patch:

      * Make absent-arg wrappers work for unlifted types (fix Trac #4306)
      
      Previously we were simply passing arguments of unlifted
      type to a wrapper, even if they were absent, which was
      stupid.
      
      See Note [Absent error Id] in WwLib.
