  Log Message:
  -----------
  [Verifier] Allow undef/poison in entry_values expressions.

This patch relaxes the verifier when it checks whether an OP_entry_value has a
valid Value associated with it. We now allow undef/poison values as well, since
those may be introduced naturally through optimization.
