================
Comment at: lib/Transforms/Scalar/LoopSimplifyCFG.cpp:109
   // after the constant folding.
   SmallPtrSet<BasicBlock *, 8> DeadExitBlocks;
   // The blocks that will still be a part of the current loop after folding.
----------------
We generate switches basing on this, and `SmallPtrSet` has a non-deterministic order. Need underlying NFC to make it a vector.
