[Mesa-dev] [PATCH 2/3] r600: add register info for atomic counters.

[Dave Airlie]

From: Dave Airlie <airlied at redhat.com>

The atomic counters on evergreen are implemented via append/consume
UAV counters. This just adds the register info for them. The EOS
packets are used to get the atomic totals extracted post shader
execution for storing into a buffer.
