Subject: [PATCH] gallium: add PIPE_SHADER_CAP_MAX_UNROLL_ITERATIONS_HINT
This avoids a serious r600g bug leading to a GPU hang.
The chances this bug will get fixed are pretty low now.
I deeply regret listening to others and not pushing this patch, leaving
other users with a GPU-crashing driver. Yes, it should be fixed
in the compiler and it's ugly, but users couldn't care less about that.
