Add opcode test to suites

[yijiasu-crypto]

Closes: #XXX

Description

Add some opcode test from the original go-ethereum protocol. Original test files can be found here: https://github.com/ethereum/go-ethereum/tree/master/tests/solidity

The opcode test will ask EVM to run all opcode defined by Ethereum Yellow Paper to make sure the EVM performs correctly.

Run yarn test --network ethermint opcode to perform this test.

this looks good but I'm afraid the contracts on geth were updated for the last time 2 years ago so there might be a few opcodes missing. Can you check that and add them too if possible?

Also, if you could add a README.md on the opcode/ directory to run the tests that would be amazing

Sure. Will do

@yijiasu-crypto are you going to add the opcodes? or should we add them on a separate PR?

[yijiasu-crypto]

Yes I think we could just merge this.

I will issue a separate PR to add more opcode tests.

@yijiasu-crypto can you create an issue to keep track of progress?
