--- Comment #117 from Dmitry Selyutin <ghostmansd at gmail.com> ---
I still had to make it somewhat more complex, because self.call will not do
anything, only `yield from self.call` will. Also, since basically our insn flow
is unchanged, but we have to "inject" rfid instruction, I had to be somewhat
creative.

I also had to introduce a way to pass initial_msr parameter into test_runner.

One this is done, almost everything works, except MSR check:
