[#1049] Optimise GREATEST() and LEAST() simulations for Sybase, ASE, SQL Server, Derby - added more integration tests for GREATEST() and LEAST(). In case these functions are simulated using subqueries, MAX() and UNION ALL(), be sure that all dialects still support them, even they only have limited support for derived tables.
