The GLSL precision lowering is still buggy (see !10729), no other driver
enables all the CAPs yet. I don't know enough GLSL IR to be the one to
fix this. In the mean time, this is a hotfix to expose the same set of
CAPs that radeonsi does.
By keeping it with is_deqp, we still get CI coverage of int16.
