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.

That sounds good to me too. Peter, what do you think about this?
