[Alexander Marshalov]

New submission from Alexander Marshalov:

Missed peephole optimization:
   1 > 2  ->  False
   3 < 4  ->  True
   5 == 6  ->  False
   6 != 7  ->  True
   7 >= 8  ->  False
   8 <= 9  ->  True
   10 is 11 -> False
   12 is not 13  ->  True
   14 in (15, 16, 17)  ->  False
   18 not in (19, 20, 21)  ->  True
