Which is "i965/nir: Enable SIMD16 support in the NIR FS backend."  This
probably means that we're generating a SIMD16 shader on ILK that is invalid on
that hardware.

Can you provide the output of 'INTEL_DEBUG=fs' with and without INTEL_USE_NIR? 
That should help narrow down which shader is incorrectly getting SIMD16.
