Subject: [PATCH] Fix constant < > <= >= evaluation

- SendExprCommand() evaluated all four of these as their inverse. I
  wouldn't at all be surprised if this was caused by me fixing the
  undefined behavior (Which PopExStk() is called first?) and not
  even noticing that these were reversed because they popped off the stack
  in reverse order.
