NT went from 27M c/s down to 18M c/s from the more work put in bench.c.

I think it would be correct to add this new "test method". I had a look 
at format->params.benchmark_length and it appears if you set it to a 
positive number (eg 8) there will be separate figures for lengths <=8 
and length >8. Perhaps we could add this new "test method" as -2 and 
still report it as one salt/many salts.
