Sergey Glukhov 649deaa8a1 Bug#52124 memory leaks like a sieve in datetime, timestamp, time, date fields + warnings ...

Arg_comparator initializes 'comparators' array in case of
ROW comparison and does not free this array on destruction.
It leads to memory leaks.
The fix:
-added Arg_comparator::cleanup() method which frees
 'comparators' array.
-added Item_bool_func2::cleanup() method which calls 
 Arg_comparator::cleanup() method
