--- Comment #1 from Adam Nemet <anemet at apple.com> ---
It was an overeager assert.  I fixed it in r264081:

    When you have multiple LCSSA (single-operand) PHIs that are converted
    into two-operand PHIs due to versioning, only assert that the PHI
    currently being converted has a single operand.  I.e. we don't want to
    check PHIs that were converted earlier in the loop.
