Comment (by teor):

 nickm suggests that we just use i128, and wait to see if the unit tests
 fail.
 (In most cases, the compilation will fail, so it will be obvious.)

 If we want the fastest code, we should select 32-bit multiplications on
 some platforms, see:
 https://github.com/dalek-cryptography/curve25519-dalek/issues/126
 But that's not a high priority for us.
