This hardware hang workaround (PAL waMiscPopsMissedOverlap) is needed only
on some Vega chips, and only for 8 or more samples per pixel. It has a
significant performance cost (around 1.5x-2x in
nvpro-samples/vk_order_independent_transparency), so it should be precisely
configured when setting up Primitive Ordered Pixel Shading.
It was added in 47b780be21, when POPS was not
used in Mesa, with the change being described as "this may not be needed
yet, but let's set it now".
