MXS-1307 CTE tests pass
There are some issues still - With recursive CTEs qc_mysqlembedded and qc_sqlite agree upon the real columns, but disagree on the CTE related "virtual" columns. That's largely irrelevant though. - qc_sqlite cannot parse "SET STATEMENT var=... FOR stmt", but it will be classified as QUERY_TYPE_GSYSVAR_WRITE. This is not directly CTE related.
