Description

The coverage statistic should be collected to improve fuzzing. To store the result of concrete execution atrie is used. For every coverage trace the total number of the same traces available to further analysis. Also, fuzzing now doesn't generate UtExecution with same coverage trace which increases a performance a bit, because fuzzing can generate a zillion combinations.
