About clang "code will never be executed [-Wunreachable-code]" warning: I compiled Python using clang -O3. There is one warning, but it's unrelated to this change:

./Modules/timemodule.c:113:13: warning: code will never be executed [-Wunreachable-code]

I tested clang version 9.0.0 (Fedora 9.0.0-1.fc31).

Add _Py_NO_RETURN to functions calling Py_FatalError():

* _PyObject_AssertFailed()
* dummy_dealloc()
* faulthandler_fatal_error_thread()
* none_dealloc()
* notimplemented_dealloc()

Note: marking _PyObject_AssertFailed() with _Py_NO_RETURN idea comes from a GCC 10 regression bug report: https://gcc.gnu.org/bugzilla/show_bug.cgi?id=93384#c17
