Fixed two bugs with CREATE OR REPLACE and LOCK TABLES:

Browse Source 
MDEV-6560 Assertion `! is_set() ' failed in Diagnostics_area::set_ok_status on killing CREATE OR REPLACE
MDEV-6525 Assertion `table->pos_in_locked _tables == __null || table->pos_in_locked_tables->table = table' failed in mark_used_tables_as_free_for_reuse, locking problems and binlogging problems on CREATE OR REPLACE under lock.
 

mysql-test/r/create_or_replace.result:
  Added test for MDEV-6560
mysql-test/t/create_or_replace.test:
  Added test for MDEV-6560
mysql-test/valgrind.supp:
  Added suppression for OpenSuse 12.3
sql/sql_base.cc:
  More DBUG
sql/sql_class.cc:
  Changed that thd_sqlcom_can_generate_row_events() does not report that CREATE OR REPLACE is generating row events.
  This is safe as this function is only used by InnoDB/XtraDB to check if a query is generating row events as part of another transaction. As CREATE is always run as it's own transaction, this isn't a problem.
  This fixed MDEV-6525.
sql/sql_table.cc:
  Remember if reopen_tables() generates an error (which can only happen in case of KILL).
  This fixed MDEV-6560
