[patch/sim] IGEN to FSF

[Andrew Cagney]

FYI, I've updated the copyright notices on the files in the IGEN 
directory so that they reflect current reality:

2002-11-21  Andrew Cagney  <ac131313@redhat.com>

         * Makefile.in: Update copyright.  IGEN contributed to the FSF.
         * filter.c, filter.h, filter_host.c, filter_host.h: Ditto.
         * gen-engine.c, gen-engine.h, gen-icache.c, gen-icache.h: Ditto.
         * gen-idecode.c, gen-idecode.h, gen-itable.c: Ditto.
         * gen-itable.h, gen-model.c, gen-model.h, gen-semantics.c: Ditto.
         * gen-semantics.h, gen-support.c, gen-support.h, gen.c: Ditto.
         * gen.h, igen.c, igen.h, ld-cache.c, ld-cache.h: Ditto.

         * lf.h, misc.c, misc.h, table.c, table.h: Ditto.

I no longer own this code :-)

I'll be pulling this into 5.3 shortly (best get it to match reality 
before the release).
