I don't think that would make much sense to get rid of the vector. At
the moment, with O(1) add/remove it's pretty optimal, even better than
unchain_marker which is O(N). And the marker stuff is used really often.

But I'm only speaking for myself. If it's easier to support IA32 that
way, please feel free. I'm fine with it, really, not the least because
I'm using some other Emacs :-).
