This would usually be in a patch just modifies code in
src/mesa/drivers/dri/i965 or a patch by itself.  Also, update
docs/features.txt and docs/relnotes/.

This change should be added in the same patch that adds
ARB_transform_feedback_overflow_query in mtypes.h.  See
https://cgit.freedesktop.org/~idr/mesa/commit/?h=ARB_transform_feedback_overflow_query&id=7eaf174d7a28c52b717a38896c1e782302fcd87f.

Does anything use this?
