AES instruction set for hashing.

[master...@gmail.com]

I want to ask Cityhash developers: do You think about using AES insructions (where possible) for noncryptogaphy hashing purposes. AESENC instruction takes 4-7 clocks and for hashing you will need to run it once, not 9-11 times + AESENCLAST, as it required for encryption. This may be fast enough hash function and also unpredictable enough to resist to collision predictability attack.

I've experimented with things like that, and I agree that they're promising.
