Since setting the unsafe-fp-math attribute just for vertex shaders or just for
fragment shaders was both enough to trigger the bug (break grass and hide the
GPU faults), I was just wondering if setting that attribute on one of the
shader stages somehow also affected the optimization passes and/or codegen for
the other shader stages.

I'm really not that familiar with the Mesa / Gallium internals, so thanks for
clearing that up.
