So I built mesa with debug symbols and I guess debugging enables some
assertions because now fails at some assertion about Register.Index stuff. Full
backtrace attached.

(bug 81834 doesn't say what versions he uses. I use upstream llvm 214022 and
mesa git with the small patch I mentioned)

Of course it could be both problems at the same time.
