<p dir="ltr">Thinking a bit more, I think we can get both the sampler count and the binding table entry count from the anv_bind_map data structure associated with the stage. We should either use that directly or plumb it through prog_data somewhere. (I don't believe we fill of those prog_data fields today.)</p>
