autoconf.
* gencode.c (write_opcodes): Pad operands field to account for
MSVC braindamage.
* simops.c: Include errno.h. Exclude SYS_chown, since MSVC
doesn't support it. (Why is this here in the first place?!?)
* v850_sim.h: Get rid of 64 bit defs. Also, get rid of #elif's.
Change number of operands in struct simops from 9 to 6. Define
SIGTRAP and SIGQUIT for MSVC.

and patterns.
* interp.c (sim_resume): Save and restore PC from the appropriate

* (sim_fetch_register sim_store_register): Fix byte-order problem
with reading and writing registers.
* simops.c (OP_FFFF): Implement pseudo-breakpoint insn.

Remove test code. Remove #if 0 code.
* interp.c: Provide prototypes for all static functions.
Fix minor indention problems.
(sim_open, sim_resume): Remove unused variables.
(sim_read): Return type is "int".
* simops.c: Remove unused variables.
(divh): Make result of divide-by-zero zero.
(setf): Initialize result to keep compiler quiet.
(sar instructions): These just clear the overflow bit.
* v850_sim.h: Provide prototypes for put_byte, put_half
and put_word.
Cleaning up.
