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 appear=
s 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.
