Replace static variables in the MSP430 simulator with fields in the cpu state structure.

Browse Source 
* msp430-sim.c: Move static hardware multiply support variables
	from here...
	* msp430-sim.h (msp430_cpu_state): ... into here ...
	* msp430-sim.c (get_op, put_op): ... and update references to use
	the msp430_cpu_state structure.
