Thanks, just one nit.



================
Comment at: llvm/lib/CodeGen/SelectionDAG/DAGCombiner.cpp:15670
+SDValue DAGCombiner::visitLIFETIME_START(SDNode *N) {
+  if (SDValue V = ImproveLifetimeNodeChain(N))
+    return V;
----------------
This can be simplified to:

```
return ImproveLifetimeNodeChain(N);
```
