Originally intended for #3529, but this can be used as standalone.
This PR creates a very simple "opcode benchmark". It reads all stack information from
stackDeltafrom EOF. Note: this stack delta only contains opcodes available in EOF, so opcodes asCALLare not in there.The benchmark simply setups the stack with the right amount of inputs (all zeros), then performs the operation, and then pops any outputs if the opcode has them. Then it jumps back (it loops forever). This is obviously a very naive test, for instance for the ADD opcode it will thus keep performing
0 + 0the entire time.
