//! Compute "magic numbers" for division-by-constants transformations.
//!
//! Math helpers for division by (non-power-of-2) constants. This is based
//! on the presentation in "Hacker's Delight" by Henry Warren, 2003. There
//! are four cases: {unsigned, signed} x {32 bit, 64 bit}. The word size
//! makes little difference, but the signed-vs-unsigned aspect has a large
//! effect. Therefore everything is presented in the order U32 U64 S32 S64
//! so as to emphasise the similarity of the U32 and U64 cases and the S32
//! and S64 cases.
