Shouldn't all these have >= CONSTANTINOPLE?
E.g. (rev >= istanbul) elseif (rev == constantinople) else .. (because it was disabled in petersburg)

This doesn't seem to work right: for PUSH1 0 PUSH1 0 SSTORE with 2306 starting gas, at the beginning of SSTORE state.gas_left is 2300 and correction is 6

got it, arg.p.number should be filled for SSTORE in analysis
