Move recent_rotated and recent_scanned prints next to inactive_anon,
ative_anon, inactive_file, active_file, and unevictable prints to
save developers' time. Since they have to go a long way(when cat memory.stat)
to find recent_rotated and recent_scanned prints which has relationship
with the memory cgroup we care. These prints are behind total_* which
not just focus on the memory cgroup we care currently.

The hierarchical stats are about that memcg, too.  And I don't want to

Move recent_rotated and recent_scanned prints next to file lru lists
just because the pageout code in vmscan.c keeps track of how many of 
the mem/swap backed and file backed pages are referenced, and the 
higher the rotated/scanned ratio, the more valuable that cache is. 
Move five lru lists and associated debug informations together can 
make things convenience. :-)

turn on debugging and then look for the extra information hiding in
the middle of regular stats.
