In this, we want to only push on a candidate sub if the arity of the sub
matches the arity of the MMD call? If so, what do we compare it to?

Also, do we need to check the arity of MultiSub candidates too?

Are we sure that Parrot_mmd_maybe_candidate is the right place to be
checking arity on these subs?
