-/* mpn_submul_1 -- multiply the S1_SIZE long limb vector pointed to by S1_PTR
-   by S2_LIMB, subtract the S1_SIZE least significant limbs of the product
-   from the limb vector pointed to by RES_PTR.  Return the most significant
-   limb of the product, adjusted for carry-out from the subtraction.
