Benchmarks!

[mhluongo]

We need benchmarks against all parameters of F that will be exposed in the go-ethereum precompile. Ideally, we want something similar to what we put together for EIP-1108 so we can get gas estimates.

Benchmarks prepared and confirmed by Ethereum devs. See ethereum/EIPs@7cd9f95

I am closing this issue, there is nothing more left to be done here.
