I'm pretty sure this is a bug in the scheduler.  I'm attaching screenshots
comparing running with this patch:
https://bugs.freedesktop.org/attachment.cgi?id=42514 to running with
RADEON_DEBUG=noopt.  The screenshots look very similar, but I think the shadow
with RADEON_DEBUG=noopt is darker.

As for performance difference between RADEON_DEBUG=noopt and with
optimizations.  I think we are seeing this because Lightsmark compiles new
shaders while running the benchmark and the longer compile time for optimized
shaders is lowering the FPS.
