MyRocks and sql-bench

MyRocks is now able to run sql-bench with support recently added for tables that are missing a PK. I found one bug and two performance problems in MyRocks when running sql-bench.

While writing this I found a post that claims sql-bench will be removed from the MySQL repo. It is useful and I hope it remains in some repo.

I run sql-bench for MyRocks with this command line:

./run-all-tests --server=mysql --create-options="engine=rocksdb default collate latin1_bin"
