In the Car Visualizer Webgl demo, there are some flickering black spots on the
car. This is probably a bug in the shader compiler, as RADEON_DEBUG=noopt works
around this. Specifically its the register_rename pass that causes this, when
it is disabled in r3xx_fragprog.c, everything is fine. Also when I disable only
the dataflow optimize pass, there is still some flickering but much less.
