Some different with GP
Cannot implement ι ≠ ∅ , so check if ι is next block's start instruction

Ditto. Since cannot assign ∅ to ι, just update and check in the upper func. ι will not be returned.
I think this change might be reasonable.

implementation version: gas model
TODO: check the implementation is stick to the new 0.8.0 Graypaper gas model.
Testing
Once gas model is implemented, the implementation needs to be integrated with the test vectors.
