nv50/ir: use levelZero for non-frag tex/txp ops
radeonsi also does the same thing. I suspect that this is likely to be a no-op in reality, but it brings nouveau code closer to what the blob produces. Plus it makes sense to not try to do auto-derivatives on this. Signed-off-by: Ilia Mirkin <[email protected]> Reviewed-by: Samuel Pitoiset <[email protected]>
