failing tgsi shader
This happens in GRID Autosport, when selecting one of the advanced graphics
options (global illumination or the one right next to it). The issue appears to
be squarely in nouveau's optimizations.
It looks like we end up deciding that the first while loop can be removed? Or
somehow lose track of those BBs? Unclear. This in turn leads to BB:11 being
completely lost.</pre>
