                                       MCContext &Context) {
+  Expected<std::unique_ptr<MCStreamer>> MCStreamerOrErr =
+      createMCStreamer(Out, DwoOut, FileType, Context);
----------------
Changes in this file are related to MCContext lifetime. MCContext is owned by MMI which is allocated & owned by the MachineFunctionAnalysisManager. Doing this allows us to delay the creation of MCStreamer when AsmPrinter is added to the pipeline.
