* gencode.c (write_header): Add "insn" and "extension" arguments

        to the OP_* declarations.
        (write_template): Similarly for function templates.
        * interp.c (insn, extension): Remove global variables.  Instead
        pass them as arguments to the OP_* functions.
        * mn10300_sim.h: Remove decls for "insn" and "extension".
        * simops.c (OP_*): Accept "insn" and "extension" as arguments
        instead of using globals.
Starting to clean things up.
