The tests aren't divergent and if support ever gets added it will happen automatically. It's an attribute in LLVM-IR, so it's perfectly legal to have in LLVM-IR. I was mulling over whether or not it should get a warning or something if it's present on an unsupported platform when we do the lowering.
