The ValueEvolution logic is deeply flawed, and checking that zero-bits are shifted can be exploited for miscompiles. In an effort to redo HashRecognize with a pattern-matching based approach, extract and fix the core logic of ValueEvolution, and strip it completely, showing that none of the tests rely on the KnownBits computation of ValueEvolution.
