1335 instructions. Make the simulator stop when a halt
1336 instruction is encountered. Very crude support for
1337 emulated syscalls (trap 0).

1339 v850_callback. Items in the operand array are 32bits.

1418 (sim_resume): Tweak to deal with format 1 and format 2
1419 handling in a single funtion. Don't update the PC
