[commit] Specify isa(s) when doing ifield, operand, insn lookups.

[Doug Evans <dje at sebabeach dot org>]

Hi.

fyi, I checked in this patch.
It fixes a bug in the sh64 gdb sim generation which I didn't detect
earlier because of a missing rule in sim/sh64/Makefile.in (now fixed).
Plus it's been on the todo list for awhile.

This is the last patch that's been holding me back from updating
all the simulator files in gdb.

Not all calls to current-op-lookup,current-ifld-lookup specify an isa,
but this patch was getting big so I left further cleanups for another pass.

Tested by running "gen-all all", checking the diffs, and running the
testsuites for frv, m32r, sh64 sims.
[gen-all is a new script for building the world and generating diffs
to look for regressions]
