[Mesa-dev] [PATCH] radv: allow to use a compute shader for resetting the query pool

[Samuel Pitoiset]

Serious Sam Fusion 2017 uses a huge number of occlusion queries,
and the allocated query pool buffer is greater than 4096 bytes.

This slightly improves performance (tested in Ultra) from
117.2 FPS to 119.7 FPS (~+2%) on my RX480.
