37379a256b 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.

c02ed6a8a3 For bfd, add vr5400 and vr5000 mips machine variants to list of machines.

more work later).

7ce8b9178c IGEN likes to cache the current instruction address (CIA). Change the

(the global previously used) when the simulation halts.

525d929e49 Rewrite sim_monitor (implements read, write, open, et.al. system
calls) and sim_open so that they uses the virtual memory data transfer
functions sim_read & sim_write.  This eliminates all code (other than
in load_memory & store_memory) that makes assumptions about the
implementation of the underlying memory model.
