To address teminator lifetime insertion issue. Rebased for https://reviews.llvm.org/D155571

- don't insert if the lastuser is the terminator for the BB,
  - This requires PostDominatorTree, so coming patch insert this, I believe the absence of the `lifetime.end` is not so much an issue ;) I'll appreciate if you tell me if it matters.
