IGEN - Replace IMEM (IMEM_IMMED) macro with IMEM<insn-size> macro,
...
update v850, tic80 and mips simulators.
IGEN - Prepend prefix to more generated symbols and macros
(idecode_issue, instruction_word).
IGEN - Add -Wnowith option to supress warnings about word size
inflicts in input files.
MIPS - Clean up Makefile.in, m16.igen, m16.dc (new), m16run.c (new) so
that a mips16 simulator built using IGEN can be compiled.

Clarify meaning of sim_signalled's SIGRC argument. Document that this
...
isn't possible in sim-reason.c and just return the target SIGRC
instead.
For simulators that rely on sim-reason.c, replace SIG* with SIM_SIG*.
Hack nrun.c so that when it is executed (ARGV[0]) as `step' instead
of `run' it single steps the simulator. Allows testing of single step
without full GDB.
