Do we even really need this?
I'd suggest removing it entirely. You might want to retain the whole
compiletime_assert_atomic_type()
thing on purely the alpha side, but then it's all inside just the
alpha code, without any need for this "native_word" thing.
And if somebody tries to do a "smp_store_release()" on a random
structure or union, do we care? We're not some nanny state that wants
to give nice warnings for insane code.
