This is a subset of the previous fuzzing bugfix/improvement series, which is the minimum required to avoid hitting assertions in the emulator.
From a 4.9 point of view, this entirely userspace testing harness changes (so safe to take), but it allows us to sensibly fuzz the emulator in the hypervisor (rather than hitting a load of assertions).
