So these functions are preceded by the comment:
/* Legacy unaligned versions. Note that we never had a complete set. */
which suggests that we shouldn't be adding new ones.
I think the correct answer is to use lduw_be_p() directly.
(If so it's tempting to get rid of the legacy functions
completely since the change would be pretty mechanical.)
