cleanup
* use compile_time_assert instead of DBUG_ASSERT * don't use thd->clear_error(), because * the error was already consumed by the error handler, so there is nothing to clear * it's dangerous to clear errors indiscriminately, if the error came from outside of read_statistics_for_tables() it must not be cleared
