[PATCH] D42247: [Dominators] Fix some edge cases for PostDomTree updating

Thanks.

No objections from me. I don't know of any way that current in-tree passes will trigger these, they mostly come from batch updating post dom trees, which is not something I think happens just yet. They should be safe to go into the branch, if you think thats best.
