radeonsi is designed such that nonbindless and bindless arrays of
binding slots are separate. You either get a nonbindless index within
nonbindless per-shader slots, or you get a bindless handle that is an
index into bindless slots. We could merge those arrays of binding
slots into one, though at the cost of added CPU overhead. So we are
not going to do that. This is one of the weird things that get added
into the spec even though they are unnecessary.
