9-Way RadeonSI GPU Tests On Mesa 17.1 + Linux 4.11

Civilization VI appears to still have some heavy performance issues or bottlenecks for RadeonSI Gallium3D. While recent tests looked like my notorious Radeon R9 290 was back to performing correctly with the latest Linux DRM code, at least for some tests it's still showing weird behavior -- likely due to odd clocking decisions.

Some DiRT Rally numbers for those interested, again with this particular Radeon R9 290 showing the biggest oddity.

Dota 2 ran fine at 1080p on all the tested hardware except for the R9 290.

And the Dota 2 Vulkan numbers for the AMDGPU-default hardware.
