Fixed bug #16069.

Browse Source 
The function agg_cmp_type in item_cmpfunc.cc neglected the fact that 
the first argument in a BETWEEN/IN predicate could be a field of a view.
As a result in the case when the retrieved table was hidden by a view 
over it and the arguments in the BETWEEN/IN predicates are of 
the date/time type the function did not perform conversion of 
the constant arguments to the same format as the first field argument.
If formats of the arguments differed it caused wrong a evaluation of
the predicates.
