Use DEBUG_SYNC to hang the execution at the interesting point, and then kill and restart the server externally. This will work also with Valgrind. DBUG_SUICIDE() causes Valgrind to hang, and it could also cause uninteresting reports about memory leaks. While we are at it, let us clean up innodb.innodb_bulk_create_index_debug so that it will actually test the desired functionality also in future versions (with instant ADD COLUMN and DROP COLUMN) and avoid some unnecessary restarts. We are adding two DEBUG_SYNC points for ALTER TABLE, because there were none that would be executed right before ha_commit_trans().
