Shorten mem_cgroup_reclaim_iter.last_dead_count from unsigned long to
int: it's assigned from an int and compared with an int, and adjacent
to an unsigned int: so there's no point to it being unsigned long,
which wasted 104 bytes in every mem_cgroup_per_zone.

Putting this one first as it should be nicely uncontroversial.
I'm assuming much too late for v3.13, so all 3 diffed against mmotm.
