Hi Baranidharan,

thank you for the patch. Could you please add a test case as well (e.g. the .ll file from llvm.org/PR32536, minimized as far as possible and a `CHECK:`-line for something that is relevant. e.g. that the `%num.0 = phi i32 [ %add, %for.body15 ], [ 0, %for.cond13.pre_entry_bb ]` is in the right position)



================
Comment at: lib/CodeGen/BlockGenerators.cpp:784
       llvm_unreachable("Unexpected statement type found");
+  // Invalidate SCEV of loops surrounding EscapeUsers
+  for (const auto &EscapeMapping : EscapeMap) {

Please add a newline before.
