Remove accidenatlly committed debug printfs when query cache is used
sql_update.cc, sql_load.cc, sql_insert.cc, sql_delete.cc:
  For the transactional query cache algorithm to work we must invalidate the query cache in INSERT/DELETE/UPDATE before writing to the binlog or calling ha_autocommit_... Note that binlog writing may also call commit. The crucial thing is that the transaction which modified data must not be committed BEFORE the query cache is invalidated.
