Bug#57095: Wrongly chosen expression cache type led to a wrong result.
The coalesce function returned DATETIME type due to a DATETIME argument, but
since it's not a date/time function it can't return correct int value for
it. Nevertheless Item_datetime_cache was chosen to cache coalesce's result
and that led to a wrong result.
Now Item_datetime_cache is used only for those function that could return
correct int representation of DATETIME values.
