[PATCH] D25225: Add an option to save the backend-produced YAML optimization record to a file

+        Ctx.setDiagnosticsOutputFile(new yaml::Output(OptRecordFile->os()));
+      }
----------------
Sorry, one more thing: if PGO is available, I think we want to set Ctx.setDiagnosticHotnessRequested as well.  Without that, you'd have to pass -fsave-optimization-record and -fdiagnostics-show-hotness to get hotness info into the YAML file which feels strange.  I am certainly fine if we do this later but I wanted to bring it up since it's seems related.
