3 byte instructions.

FMT_D9 and FMT_D10. Handle various new opcode flags for the am33.
(mn10300_opcodes): Reorder so as to try and select opcodes from
the core chip when multiple alternatives exist. Change several

"macbu" instructions. Fix typos in a couple DSP instructions too.
printing references the symbol table to determine whether the
instruction resides in a block regular instructions or mips16
instructions. However, when the disassembler gets used in other
environments where the symbol table is not present, we no longer
rely in the symbol table, rather, use the low bit of the
instructions address to guess. There should be no change for usage
of the disassembler in host based programse, gdb ,objdump.

of aad and aam (Ib -> sIb). Change ud2b from 0fb8 to 0fb9 to
agree with Intel docs.

Return correct byte count for orphan fwait with prefixes. Don't
print `bound' operands in reverse order.
