    sigurds authored
    * Treat Select nodes as escaping
    * Correctly void virtual field information
      after a store to a non-const index
    * Add a shortcut if all allocates escape
    * Add a shortcut if no allocates are discovered
    * Only reduce FrameState/StateValues nodes if they
      have virtual allocates as input (transitively)
    * Fix bug in FrameState/StateValues duplication
    * Add check to verifier: First 3 inputs of FrameState
      must be StateValues
