Kirill Tkhai fae91d6d8b mm/list_lru.c: set bit in memcg shrinker bitmap on first list_lru item appearance 
Introduce set_shrinker_bit() function to set shrinker-related bit in
memcg shrinker bitmap, and set the bit after the first item is added and
in case of reparenting destroyed memcg's items.

This will allow next patch to make shrinkers be called only, in case of
they have charged objects at the moment, and to improve shrink_slab()
performance.
