[LoopUnroll] Don't update DT for changeToUnreachable.
There is no need to update the DT here, because there must be a unique
latch. Hence if the latch is not exiting it must directly branch back
to the original loop header and does not dominate any nodes.
Skipping a DT update here simplifies D141487.
