Ah, it seems I just compared wrong results when I was testing all
combinations of backends and looked for regressions.
Now I think the problem is that even though llvm backend correctly emits
color export with nr_c

Are there any piglit tests for that? I didn't see any regressions with
this patch (at least on evergreen), possibly I messed up the testing
somehow. Also I think old b
Like Christoph said, COLOR0 (if available) must always be exported for
alpha test.
