//
// This pass is designed to be a very quick global transformation that
// eliminates global common subexpressions from a function. It does this by
// examining the SSA value graph of the function, instead of doing slow, dense,
// bit-vector computations.
// using an existing value numbering implementation to identify the common
// subexpressions, eliminating them when possible.
