Tiling group size is always 256bits on r6xx/r7xx/r8xx/9xx. Also fix and simplify render backend map. This now properly sets up the backend map on r6xx-9xx which should improve 3D performance.
It would be great if you could give some benchmark data confirming that should. Or tell users what tests to run to get some data.

Some benchmarks on juniper (5750), fullscreen 1920x1080, first result - kernel 3.4.0+ (fb21affa), second - with these patches:
Lightsmark: 91 fps => 123 fps +35% Doom3: 74 fps => 101 fps +36%
