cleanup_all_empty_eh is called just once per ehcleanup pass, doesn't iterate.
If we don't want to iterate on the new pads, we could just use len = VEC_length
too, but IMHO some iteration is helpful, as we don't recurse on them, and we
probably want to handle cases like moving pads across two empty bbs and with a
resx in the third bb or something similar.
