This one was actually an accidental recommit and noop (due to a problem in
my git working directory) of something Daniel committed the day before:

[llvm] r306792 - Revert "r306473 - re-commit r306336: Enable
vectorizer-maximize-bandwidth by default."

(so the comment about forwarding a repro to Dehao was Daniel's not mine).

Hopefully Daniel and/or Dehao can follow up with the status.

Thanks,
Teresa
