The tests need an update for this change. And the same GCC built-ins can
also be used in the module 'pthread-spin'.

pthread-spin: Use GCC built-ins also on clang.
* lib/pthread-spin.c (pthread_spin_init, pthread_spin_lock,
pthread_spin_trylock, pthread_spin_unlock): Use the newer GCC built-ins
also on clang.

asyncsafe-spin tests: Update.
* tests/test-asyncsafe-spin2.c: Update to match the change in
lib/asyncsafe-spin.c from 2020-08-11.
