RADEON_DEBUG=fp,vp

In Anno1701, there are flickering colorful spots over some models. It looks
similar to the bug 60552, except the spots are colorful instead of black and
they don't go away with RADEON_DEBUG=noopt. 

Setting Wine to use ARB shader rendering backend instead of GLSL makes the
problem go away indicating another bug in the shader compiler. 

Apitrace here http://pavel.ondracka.cz/Anno1701.trace (renders fine with
proprietary NVIDIA drivers).

Wine: 1.5.23
GPU: RV530
Mesa: f1ab67c13ab97f19c08d99c6ba101edc7d7b80e6
Kernel: 3.7.3-101.fc17.i686
