* This handler encapsulates heap memory ops for selfVerification mode.
* The call to the handler is inserted prior to a heap memory operation.
* This handler then calls a function to decode the memory op, and process
* it accordingly. Afterwards, the handler changes the return address to
* skip the memory op so it never gets executed.
