Lei Jin 0d755fff14 cache friendly blocked bloomfilter 
Summary:
By constraining the probes within cache line(s), we can improve the
cache miss rate thus performance. This probably only makes sense for
in-memory workload so defaults the option to off.

Numbers and comparision can be found in wiki:

Test Plan: benchmarked this change substantially. Will run make all check as well
