Jelle Raaijmakers 1745926fc6 AK+Everywhere: Use MurmurHash3 for int/u64 hashing 
Rework our hash functions a bit for significant better performance:

* Rename int_hash to u32_hash to mirror u64_hash.
* Make pair_int_hash call u64_hash instead of multiple u32_hash()es.
* Implement MurmurHash3's fmix32 and fmix64 for u32_hash and u64_hash.

On my machine, this speeds up u32_hash by 20%, u64_hash by ~290%, and
pair_int_hash by ~260%.

We lose the property that an input of 0 results in something that is not
0. I've experimented with an offset to both hash functions, but it
resulted in a measurable performance degradation for u64_hash. If
there's a good use case for 0 not to result in 0, we can always add in
that offset as a countermeasure in the future.
