Remove block gas optimization

[rakita]

Block gas optimization what moves counting gas from instruction level to the block of instruction was the intuitive idea that I thought would optimize execution, the results were not as expected. It became difficult to calculate gas in Inspector, and there was even a bug introduced by it, Analyzed bytecode become bigger and optimization was just a few percentages.

It is not worth keeping it and the main reasons for removal are bigger analyzed bytecode size and complexity of usage.
