Back out changeset e1c85e8a23b1 for investigation on Windows 32-bits.

I think this^ was a typo -- e1c85e8a23b1 doesn't seem to be an actual commit ID. At least, these are both error pages:
https://hg.mozilla.org/integration/autoland/rev/e1c85e8a23b1
https://hg.mozilla.org/mozilla-central/rev/e1c85e8a23b1

I think you maybe meant to point at e2e3a95faccd (i.e. https://hg.mozilla.org/integration/autoland/rev/e2e3a95faccd ) -- that seems to be what this commit is conditionally reverting.
