I think this is the wrong approach. What we really want to do is kill tests from kms_flip
instead and move them to separate places.

Killing off all the interruptible tests would save 50% of the time. So all we have to do is
making sure that we have tests that test the missing ioctl's in in kms_atomic_interruptible,
and we would save 50% of the time.

After that we have to get rid of the unrelated tests to make the code more readable..
nonexisting-fb, dpms-vs-vblank-race, modeset-vs-vblank-race and bo-too-big would be
better off in a separate testcase.

Same for bad-tiling, but I already had a patch for that.

This would clean up kms_flip a lot, and make the test more readable.
