AMD's Latest Open-Source Driver On Linux Is Getting Competitive With Catalyst 15.7

For the other synthetic OpenGL tests, the Radeon Gallium3D results were in decent shape except for the triangle test that's mostly limited by video memory bandwidth showing the open-source AMD Linux driver has a ways to improve against Catalyst. The HD 7950 on Catalyst 15.7 was strangely unstable for the GpuTest cases on Ubuntu Linux.

Overall these results today were quite positive for the open-source AMD Linux driver with this code continuing to become more competitive with Catalyst, as far as OpenGL 2~3 test-cases are concerned until OpenGL 4.x support finishes up in Mesa and the OpenCL support in Clover Gallium3D advances further.
