    [TRAFODION-1867] Allow parallel plans for non-partitioned tables in U…

    …PD STATS.
    
    The problem is for large non-partitioned tables, UPDATE STATS will do a series of SELECTs
to compute statistics for sets of columns. The plans for these SELECTs are presently forced
to be serial for non-partitioned tables as a workaround for a long-ago compiler bug which
seems to have been fixed. It's time to remove this workaround and thereby speed up UPDATE
STATS.
