Simple Summary
Add support for blake2 cryptographic hash function

Specification
Support for Blake2 is being added in the upcoming Istanbul hardfork. The specification is in EIP-152, and a reference implementation in a client is here: https://github.com/ethereum/py-evm/blob/master/eth/precompiles/blake2.py
Function signature:
blake2b_f() -> bytes32[2]
