The driver (or preferably the hardware) should handle out of bounds
indices.

If there are problems then it's better to detect those in the debug

radeon/r200/r300: don't clean non-emitted state.

So if we don't actually emit an atom to the hw because we don't
need it in the current state (e.g. lighting related atoms when
lighting is off) then don't mark it as clean, because when
lighting gets switched on we won't emit it at all.

This fixes funky gears colors.
