* \brief Perform a known-size modular addition.
*
* Calculate `A + B modulo N`.
*
* The number of limbs in each operand, and the result, is given by the
* modulus \p N.
*
* \p X may be aliased to \p A or \p B, or even both, but may not overlap
* either otherwise.
*
* \param[out] X The result of the modular addition.
* \param[in] A Little-endian presentation of the left operand. This
* must be smaller than \p N.
* \param[in] B Little-endian presentation of the right operand. This
* must be smaller than \p N.
* \param[in] N The address of the modulus.
