S_LOCK_FREE() is used by the test program in s_lock.c, but nobody has voiced concerns about losing some coverage there. SpinLockFree() appears to have been unused since it was introduced by commit 499abb0c0f. There was agreement to remove these in 2020, but it never happened. Since we still have agreement for removal in 2026, let's do that now.
