1308 insns. Invert 's' bit if 'ov' bit is set for some
1309 instructions. Fix 'cy' bit handling for numerous
1310 instructions. Make the simulator stop when a halt
1311 instruction is encountered. Very crude support for
1312 emulated syscalls (trap 0).
1313 * v850_sim.h: Include "callback.h" and declare
1314 v850_callback. Items in the operand array are 32bits.

1390 (do_format_6): Get operands correctly and call the target
1391 function.
1392 (do_formats_9_10): Rough cut so shift ops will work.
1393 (sim_resume): Tweak to deal with format 1 and format 2
1394 handling in a single funtion. Don't update the PC
1395 for format 3 insns. Fix typos.
