Title: (partially fix incoming) More hash function simplification

This removes several hash functions used with hashmap().

I am now getting an error I'm, at the moment more confused by:

```
/code/rust/src/test/bench/task-perf-word-count-generic.rs:175:24: 175:42 error: failed to find an implementation of trait core::cmp::Eq for 'b
/code/rust/src/test/bench/task-perf-word-count-generic.rs:175 let found = intermediates.find(key);
^~~~~~~~~~~~~~~~~~
```

Does this error message mean that the type of key used here needs to implement Eq?
