-/* Given a magic divisor, recover what we were trying to divide by.

- * Let m represent the magic divisor. By definition, m is an element on Z, whre
- * 0 <= m < 2^N, for N bits in m.
- *
- * Let q represent the number we would like to divide by.
- *
- * By definition of a magic divisor for N-bit unsigned integers (a number you
- * multiply by to magically get division), m is a number such that:
- *
- * (m * x) & (2^N - 1) = floor(x/q).
- * for all x on Z where 0 <= x < 2^N
- *
- * Ignore the case where any of the above values equals zero; it is irrelevant
- * for our purposes (instanced arrays).
- *
- * Choose x = q. Then:
- *
- * (m * x) & (2^N - 1) = floor(x/q).
- * (m * q) & (2^N - 1) = floor(q/q).
- *
- * floor(q/q) = floor(1) = 1, therefore:
- *
- * (m * q) & (2^N - 1) = 1
- *
- * Recall the identity that the bitwise AND of one less than a power-of-two
- * equals the modulo with that power of two, i.e. for all x:
- *
- * x & (2^N - 1) = x % N
- *
- * Therefore:
- *
- * mq % (2^N) = 1
- *
- * By definition, a modular multiplicative inverse of a number m is the number
- * q such that with respect to a modulos M:
- *
- * mq % M = 1
- *
- * Therefore, q is the modular multiplicative inverse of m with modulus 2^N.
