I think this is caused by the disassembler picking only *one* entry
out of the table and then checking the if the args match the
patterns:
{"movel", one(0020000), one(0170000), "ms%d", mcf },
{"movel", one(0020000), one(0170000), "nspd", mcf },
{"movel", one(0020000), one(0170000), "olmd", mcf },
Note that the mask and bits are the same for each pattern, its down to
the args to determine which form is valid.
To fix this I'm thinking of looping over the table for each match of
the masked opcode and if the args match, accept it.
