Description:
CREATE TABLE IF NOT EXISTS SELECT ... statements truncate the "IF NOT EXISTS" clause when using row-based binlogs.  This breaks replication.

How to repeat:
RESET MASTER;
CREATE TABLE t1 ( a int );
CREATE TABLE IF NOT EXISTS t2 SELECT * FROM t1;
CREATE TABLE IF NOT EXISTS t2 SELECT * FROM t1;
SHOW BINLOG EVENTS FROM 301\G
DROP TABLE t1, t2;

***

mysql> SHOW BINLOG EVENTS FROM 301\G
*************************** 1. row ***************************
   Log_name: abcdef-bin.000001
        Pos: 301
 Event_type: Query
  Server_id: 511
End_log_pos: 111
       Info: use `test`; CREATE TABLE `t2` (
  `a` int(11) DEFAULT NULL
)
1 row in set (0.00 sec)

Suggested fix:
n/a

  The fix makes the generated query to include the parent's statement option if that was
