Increase reductions with thread count

Respin of multi-thread idea that was simplified away recently: basically doing more reductions with thread count since Lazy SMP naturally widens search. With drawish book this idea got simplified away but with less drawish book it again gains elo, maybe trying to reinstall other ideas that were simplified away previously can be beneficial.
