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