Adam Rutkowski b4daac11c2 Track hot items on LRU list 
Top 50% least recently used cachelines are not promoted
to list head upon access. Only after cacheline drops to
bottom 50% it is considered as a candidate to promote
to list head.

The purpose of this change is to reduce overhead of
LRU list maintanance for hot cachelines.
