Alright, I finished testing the 3 problematic games which this bug affected for
me, to see how they behave with R600_DEBUG=notiling enabled. I don't use
shaders for MineCraft so I can't test them specifically, although we're
obviously talking about the same issue so this is still relevant. My results
are:

Second Life: No more GPU freeze when Advanced Lighting is enabled! This was one
of the most immediate triggers for the issue in my case, and in most scenarios
it immediately brought down the X server... now there is not a single hiccup.

Stunt Rally: No more freezes when enabling shaders! In its case however the
problem is more probabilistic, so this isn't 100% guaranteed.

One Late Night: The crash still exists, even with notiling. So there are still
cases where this variable does not solve the problem, although in most engines
it does and I'm happy enough with that for the time being.
