This re-commits r375152 which was pulled in r375233 because it broke the EXPENSIVE_CHECKS bot on Windows. The reason for the failure was a bug in the pass that the commit turned on by default. This patch fixes that bug and turns the pass back on. This patch has been verified on the buildbot that originally failed thanks to Simon Pilgrim.
