// This file implements the non-abstract Value Numbering methods as well as a
// default implementation for the analysis group.
//
// The ValueNumbering analysis pass is mostly deprecated. It is only used by the
// Global Common Subexpression Elimination pass, which is deprecated by the
// Global Value Numbering pass (which does its value numbering on its own).
