test(celo-revm): add PUSH0 regression test for fee currency debitGasFees#137
Conversation
Regression test for celo-org/op-geth#484 where fee currency contract calls used a pre-Shanghai EVM configuration, causing PUSH0 (EIP-3855) to fail. Contracts compiled with Solidity >= 0.8.20 emit PUSH0 by default, so debitGasFees/creditGasFees calls would fail. celo-kona is not affected because the spec is set explicitly via CfgEnv, but this test guards against future regressions using the real Mento StableTokenV2 (USDm) bytecode from Celo mainnet.

Now that we have the test we should merge it. We can always remove it later.

I'm not sure how useful this test is, since the problem never happened in celo-kona. So feel free to reject the PR for this reason. It will still live in GitHub to show that celo-kona is unaffected.
