[PATCH] D28168: [LV] Update dominator tree before fixing external IV users

My gut feeling is that we really want to update DT as we go.
Even if all current uses of transform() except this one are safe (and I'm not at all sure about that), leaving this as is sounds very brittle, since any additional use of transform() can potentially break it.
