Yep this is just a 'raw bisect', bug can be reproduced with master. Note that
you need Sandybridge to reproduce as the assert happens only with gen == 6. I
believe SNB needs all the swizzle channels for some particular math operation
but the new optimizations changes masks so that it is not a full mask. I can
try today if I can tackle this with a patch that bypasses mask modifications in
case we are on SNB.</pre>
