I forgot to mention this, but it should not actually be an issue in the
public branch, since that part of the information gathered there isn't
actually used by llvmpipe, hence if it contains garbage or not doesn't
matter. So there isn't really any need for stable.
But we have a branch where llvmpipe uses it.
