Michael Liao 258d9b7bc0 Enhance boolean simplification to handle 16-/64-bit RDRAND ...

- RDRAND always clears the destination value when a random value is not
  available (i.e. CF == 0). This value is truncated or zero-extended as
  the false boolean value to be returned. Boolean simplification needs
  to skip this 'zext' or 'trunc' node.
