Validator rejects valid "WITH ... ORDER BY" query

      Description

      The validator rejects a valid "WITH ... ORDER BY" query, giving the error "Aggregate expression is illegal in ORDER BY clause of non-aggregating SELECT". Example:

      with q as (select * from emp)
      select count(*) from q group by deptno order by count(*)
      

      The validator is doing a rewrite on the SqlOrderBy and is adding a wrapper SqlSelect. But its result, "select * from (...) order by count( * )" is not valid. We should instead generate "select * from (...) order by 1".
