If you look at the simulator source code, you'll see that it implements
MI_FLUSH as a specific kind of PIPE_CONTROL. And that MI_FLUSH isn't
being validated anymore. If this is all true, then this isn't a huge
change, other than exposing which PIPE_CONTROL workarounds we're
supposed to be using in the MI_FLUSH paths...
