Benchmark faster hash functions

We are interested in overall performance for index construction, i.e. both pure hashing speed and collisions amount are important. Note that there are at least 2 kinds of `t1ha` function: `t1ha0` (the fastest) and `t1ha1` (portable).

We should also measure `t1ha2` and `t1ha3` since they should have less collisions.
