sh: Kill off udivdi3 div64_32 wrapping.
Previously we've been handling udivdi3 references and wrapping them in to div64_32() automatically. This doesn't get a lot of use, however, and as akpm noted in the recent thread on l-k: http://lkml.org/lkml/2007/2/27/241 we're better off simply ripping it out and going the do_div() route if there happen to be any places that need it.
