Steven Hawkins resolved TEIID-535.
----------------------------------

    Resolution: Done

Based upon the other subquery changes it became trivial to support additional pushdowns.  At this time no new capabilities have been added, but there may be some needed as some dbms (db2) have restrictions on the usage of subqueries in a join clause.  See TestSubqueryPushdown.
