LGTM. Thanks for working through the comments.



================
Comment at: lib/Transforms/Scalar/LoopSimplifyCFG.cpp:90
+  // current loop and its preheader and do not affect preheader's reachibility
+  // from any other block. So in practice this variable set to true means that
+  // loop's latch has become unreachable from loop header.
----------------
Minor: can remove the "in practice" here.
