        TODO:Here we process prefixed view references only. What we should 
4726
 
        really do is process all types of Item_refs. But this will currently 
4727
 
        lead to a clash with the way references to outer SELECTs (from the 
4728
 
        HAVING clause) are handled in e.g. :
4729
 
        SELECT 1 FROM t1 AS t1_o GROUP BY a
4730
 
          HAVING (SELECT t1_o.a FROM t1 AS t1_i GROUP BY t1_i.a LIMIT 1).
4731
 
        Processing all Item_refs here will cause t1_o.a to resolve to itself.
4732
 
        We still need to process the special case of Item_direct_view_ref 
4733
 
        because in the context of views they have the same meaning as 
4734
 
        Item_field for tables.
