This is true, but it would break the current situation we
have where translate.c and translate-a64.c are entirely
independent and you never have to worry about breaking
one if you make changes to the other, which is why I didn't
do it. Maybe that's not very important, but it didn't seem
worth going against for the sake of a couple of helpers just
a few lines long. (If we do make them common then translate.h
would be the right place for the prototypes.)
