If SLP vectorizer tries to extend the scheduling region and runs out of the budget too early, but still extends the region to the new ending instructions (i.e., it was able to extend the region for the first instruction in the bundle, but not for the second), the compiler need to recalculate dependecies in full, just like if the extending was successfull. Without it, the schedule data chunks may end up with the wrong number of (unscheduled) dependecies and it may end up with the incorrect function, where the vectorized instruction does not dominate on the extractelement instruction.
