Add the following code where an op is scheduled. (an instruction will be executed at the following cycle)
(An in order processor should print out these messages in order.)

if (KNOB_DEBUG_PRINT.Value()) {
        cout << "ID_STAGE OP " << op->inst_id <<  " is scheduled at cycle " << cycle_count << endl; }


Add the following code where an op is retired. (right before calling the free_op function) 
 Both in order processor and out of order processor should print out these messages in order.

if (KNOB_DEBUG_PRINT.Value()) {
        cout << "WB_STAGE OP " << op->inst_id <<  " is retired at cycle " << cycle_count << endl; }
