Looks good to me, though I'm no expert on planar formats.

I'm pretty sure our HW can't do that until ICL.
2 different views on the same buffer will have the sampler pollute its
cache with invalid data from the other view.
The fact that we support this in i965 and that is passes the tests might
be pure luck (2x2 images might not be enough for the issue to manifest
itself).
I should probably try to update the tests to generate bigger images.
