This reverts commit 80cc67cc00.
Reason for revert: Not +1'd by anyone from owning team.
Original change's description:
> Add --no-squash argument to git rebase-update
>
> --no-squash makes it faster to run rebase-update when there are merge
> conflicts and you know that squashing will not help. For example, I
> store all of my branches in one commit each, so I know that squashing
> isn't even possible because they are already squashed.
