Disable instruction rewriting in the scheduler

I think this bug is actually in the scheduler, and it is just being exposed by
the reg rename pass.  I have been able to track down a few instructions that
the scheduler is converting from vector to scalar that change how the shadows
are rendered.  However, these conversions look valid too me, so I'm really not
sure what the problem is.  I think this patch fixes Lightsmark, but I'm not
sure what the shadows are supposed to look like.  Can you try this patch on
Lightsmark and Sanctuary.  Thanks.
