This PR contains two things.

1 emulate rdtsc
2 inject clock_step for qemu

What is not solved

To emulate rdtsc, we must know how many nanoseconds the VM has been running

We can get the uptime when taking the snapshot, or is there a way to get it from the memory?

injecting clock_step for qemu is done; but the performance of hyperpill will go down as the fuzzer is running
