Some minor things about the tests, otherwise LGTM



================
Comment at: test/Transforms/LoopSimplify/preserve-llvm-loop-metadata.ll:31
+; CHECK: br label %while.cond, !llvm.loop !0
+
+
----------------
The code removes the metadata from the old backedges; please add some CHECK-NOT lines to verify that.


================
Comment at: test/Transforms/SimplifyCFG/preserve-llvm-loop-metadata.ll:43
+if.end:                                           ; preds = %if.else, %if.then
+  br label %while.cond, !llvm.loop !1
+
----------------
Shouldn't this be: `!llvm.loop !0` here too.
