Must use VOID expression in VOID context.

	* xc16x.cpu (mov4): Fix mode of `sequence'.
	(mov9, mov10): Ditto.
	(movbsrr, moveb1, jmprel, jmpseg, jmps): Fix mode of `if'.
	(callr, callseg, calls, trap, rets, reti): Ditto.
	(jb, jbc, jnb, jnbs): Fix mode of `if'.  Comment out no-op `sll'.
	(atomic, extr, extp, extp1, extpg1, extpr, extpr1): Fix mode of `cond'.
	(exts, exts1, extsr, extsr1, prior): Ditto.
