I agree that toEthSignedMessageHash and toTypedDataHash functions are probably the most efficient implementations written in Solidity Assembly, btw we are using the same in @1inch: https://github.com/1inch/solidity-utils/blob/95bc66ff4267ae112f97b8296c2515a6dd999449/contracts/libraries/ECDSA.sol#L260-L282

IMO this is mostly good. Should target 4.9

at some point it was "discarded" during a merge of master into this. I cherry picked the corresponding commit to fix things.
