Correct. But it seems that libatomic library does not check existence of
cmpxchg16b. Thus it would use locked implementation even if target supports
cmpxchg16b.
i.e. old compiled code should work correctly with newly compiled code. If old
code has call to __atomic_load_16 and new code has inlined implementation -
they would work incorrectly.
