NB: Collect predecessors into a snapshot vector before iterating to avoid iterator invalidation on MBB's predecessor list. Each call to ReplaceUsesOfBlockWith modifies both the successor list of Pred and the predecessor list of MBB, which invalidates debug-mode iterators (detected by _GLIBCXX_DEBUG).
