[llvm-dev] 3-stage bootstrap build bots?

[Jack Howarth via llvm-dev]

   Do any of the current build bots for llvm.org perform 3-stage
bootstraps with file comparison of the stage2 and stage3 object files
and generated headers? On x86_64-apple-darwin16 using the fink
projects llvm packaging methodology (crafted by David Fang), I am
seeing non-deterministic file comparison failures in current trunk
that goes back as far as r296837.

The non-deterministic nature of this bug is making it rather difficult
to pinpoint the actual commit that triggered it.

ps The issue seems to be non-deterministic in both its appearance and
the exact subset of stage2/stage3 object files that differ when it
triggers.
