Subject: Old planner() becomes union_planner(); new planner() makes
 initialization of some global variables to support subselects and calls
 union_planner(). Calls to SS_replace_correlation_vars() and
 SS_process_sublinks() in query_planner() before planning. Get rid of #ifdef
 INDEXSCAN_PATCH in createplan.c.
