note: looks like there are some issues being caused in eth-tester by the new py-evm. waiting on eth-tester/py-evm maintainers to push a fix

[charles-cooper]

with ethereum/py-evm#2159 and ethereum/eth-tester#284, this PR passes all codegen tests. (there are some storage layout tests which test against hardcoded layouts; i'll switch those in a bit)
