libfuzzer has historically not supported Windows, so the reports were not
actionable.  Marcos got it working a few months ago and we had it up on a
bot, but the bot was turned down recently as we don't have time / headcount
to keep it working in the presence of other invasive changes happening on
the sanitizer side.
