* Inter-instruction transfer stub. Call out to dvmCheckBefore to handle
* any interesting requests and then jump to the real instruction
* handler. Note that the call to dvmCheckBefore is done as a tail call.
* rIBASE updates won't be seen until a refresh, and we can tell we have a
* stale rIBASE if breakFlags==0. Always refresh rIBASE here, and then
* bail to the real handler if breakFlags==0.
