OK.

I think that in general a change from a integer to a poly_uint64 should
generally be considered OK without the need for review.  Ultimately
those are highly mechanical changes with little risk for mucking
something up badly.

Obviously the changes wouldn't go in until we settled the poly_uint64
questions though.
