[Feature] Assembly Accelerated Keccak

[gakonst]

Component

primitives

Describe the feature you would like

Currently we use tiny_keccak for our keccak256 function:

core/crates/primitives/src/utils.rs

Line 30 in 0ea9024

pub fn keccak256<T: AsRef<[u8]>>(bytes: T) -> FixedBytes<32> {

.

We have a native-keccak feature for usage in Arbitrum.

We'd like to provide Keccak with assembly & accelerated instructions where possible. See @DaniPopes example usage:
https://github.com/DaniPopes/bench-keccak256/blob/127641b353c8d03fe40ca0918bee6a9991d45174/src/lib.rs#L4-L45

This yields a 15-20% improvement on keccak-asm.
