create...select processing needs to be verified

Currently create..select is not run under total order isolation, at least with ROW binlog format.
It should be verified that this does not cause issues both with ROW and STATEMENT formats.

Also, create..select with temporary table can crash the master node. This seems to happen when select contains join condition, here's a test for reproducing:

CREATE TABLE t1 (i int);
INSERT INTO t1 values (1),(3);
CREATE TABLE t2 (j int);
INSERT INTO t2 values (2),(4);
CREATE TEMPORARY TABLE tt as select t1.i, t2.j from t1, t2;

As a result, following assert will fire:

111214 11:51:37 [Note] WSREP: empty rbr buffer, query: insert into t1 values (3,3)
mysqld: galera/src/replicator_smm.cpp:812: virtual wsrep_status_t galera::ReplicatorSMM::post_commit(galera::TrxHan
