Add dg-final-scan-autofdo and dg-final-scan-not-autofdo

Autofdo outputs to different dump files and doesn't support some
transformation that normal profiling. Add dg-final-scan-autofdo
and dg-final-scan-not-autofdo statements to the test suite
so that the test cases can hande those cases separately.
