  -----------
  [clang] Fix use-after-scope when diagnosting __attribute__((format_matches))

I don't think this will ever crash, but asan complains about it.

SUMMARY: AddressSanitizer: stack-use-after-scope clang/lib/Sema/SemaChecking.cpp:6925:43 in void (anonymous namespace)::CheckFormatHandler::EmitFormatDiagnostic<clang::CharSourceRange>(clang::PartialDiagnostic, clang::SourceLocation, bool, clang::CharSourceRange, llvm::ArrayRef<clang::FixItHint>)

While there switch to stable_sort to not give a flipped error message
half of the time.
