This build bot is simultaneously really useful and really awful.

There are no coherent instructions for how I can reproduce an msan
bootstrap of Clang. But it does find real issues. The bot seems to be the
only way I learn of these, which would actually be fine if the output were
useful, but because of how lit works, the output is completely useless.

Is there any way we can make debugging these failures more reasonable for
others?

(Anyways, I'm hunting down the use-of-uninit...)
