That's probably a good idea. The shifting can be done in one place, in
the top-level sqrtrem function.

Hmm, but if we shift to make the *root* normalized, that also means that
the input will always be an even number of limbs. Not entirely sure
that's good, in particular for smallish sizes. But it ought to simplify
some things.
