    * mn10300-opc.c (FMT_XX): Renumber starting at one.
        (mn10300_operands): Rough cut.  Enough to parse "mov" instructions
        at this time.
        (mn10300_opcodes): Break opcode format out into its own field.
        Update many operand fields to deal with signed vs unsigned
        issues.  Fix one or two typos in the "mov" instruction
        opcode, mask and/or operand fields.
Checkpointing today's work.  Matsushita.
