Speaking of computing residues for small moduli m, does GMP have code to
quickly compute residues if 2^GMP_NUMB_BITS == +/-1 (mod m), by
computing the (alternating) sum of limbs and doing the modulo on that?
I'll need a fast (mod 3) for a Toom-Cook variant, is there a function to
quickly compute the sum of limbs already in there somewhere?
