[SimplifyCFG] Teach simplifyUnreachable() to preserve DomTree
Pretty boring, removeUnwindEdge() already known how to update DomTree,
so if we are to call it, we must first flush our own pending updates;
otherwise, we just stop predecessors from branching to us,
and for certain predecessors, stop their predecessors from
branching to them also.
