Bug#40825: Error 1356 while selecting from a view

           with a "HAVING" clause though query works

SELECT from views defined like:

  CREATE VIEW v1 (view_column)
    AS SELECT c AS alias FROM t1 HAVING alias

fails with an error 1356:
  View '...' references invalid table(s) or column(s)
  or function(s) or definer/invoker of view lack rights
  to use them


CREATE VIEW form with a (column list) substitutes
SELECT column names/aliases with names from a
view column list.
However, alias references in HAVING clause was
not substituted.


The Item_ref::print function has been modified
to write correct aliased names of underlying
items into VIEW definition generation/.frm file.
