Comment # 4 on bug 99013 from Christoph Haag

Which makes bisecting a lot harder, but understandable that the devs don't want
to have the burden of having many intermediate workarounds in the code that's
not used for any of the actual llvm releases.

But what I came here to say is that I have llvm 3.9.0 from the Archlinux Repos
and this commit breaks everything for me too.
