just one nit



================
Comment at: llvm/lib/Transforms/Utils/PromoteMemoryToRegister.cpp:324
+
+    I->dropDroppableUses([&](const Use *U) { return U->getUser() == UserI; });
+  };
----------------
using dropDroppableUses this way is a bit weird since it is already doing a traversal through the uses but it is correct.

maybe an API to drop a single use would be appropriate.
