In the case of Item_string::str_value we don't want
Alloced_length to be longer than str_length.
Otherwise, some functions like Item_func_concat::val_str()
try to reuse str_value as a buffer for concatenation result
for optimization purposes, so our string constant become
corrupted. See bug#8785 for more details.
Let's shrink Alloced_length to str_length to avoid this problem.
