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.
