1310 (sim_stop_reason): Gross hacks to get c-torture running.
1311 * simops.c: Simplify code for computing targets of bCC
1312 insns. Invert 's' bit if 'ov' bit is set for some
1313 instructions. Fix 'cy' bit handling for numerous
1314 instructions. Make the simulator stop when a halt
1315 instruction is encountered. Very crude support for
1316 emulated syscalls (trap 0).
1317 * v850_sim.h: Include "callback.h" and declare
1318 v850_callback. Items in the operand array are 32bits.

1321
1322 * interp.c (sim_resume): Fix code to check for a format 3
1323 opcode.
1324 * simops.c: bCC insns only argument is a constant, not a
1325 register value (duh...)

1394 (do_format_6): Get operands correctly and call the target
1395 function.
1396 (do_formats_9_10): Rough cut so shift ops will work.
1397 (sim_resume): Tweak to deal with format 1 and format 2
1398 handling in a single funtion. Don't update the PC
1399 for format 3 insns. Fix typos.

1401 to "add", "addi", "and", "andi", "or", "ori", "xor", "xori"
