these two are the wrong way round.  what the heck they are doing
in that order i have no idea.

if you look at op_mullwu_ you'll see "return (RT, overflow)".

it could be due to them being a set.  can you take a look in
pseudo/parser and pywriter and, if necessary, bludgeon
write_regs into submission?

pywriter calls back to isa.caller "create_args()" so if you
can fudge that to sort the order, making overflow always be last
in the list returned it should "work".
