Macros are tricky business and I understand why renaming is not allowed within macros. For the cases in the lit test, the renaming seems safe. Is this generally the case (i.e. those permitted by `clang::tidy::utils::rangeCanBeFixed()`)? What other test cases can we add? Or is this change just not safe? If so, how can we update the "InsideMacro" tests to actually fail even in the presence of a SourceManager.
