Testcase for BUG#7716
sql/item_cmpfunc.cc:
Fix for BUG#7716: in in_string::set() take into account that the string returned
by item->val_str(S) may be not S but use the buffer owned by S.
sql/sql_string.h:
* Added assert: String& String::operator=(const String&) may not be used to do
assignments like str = string_that_uses_buffer_owned_by_str
* Added String::uses_buffer_owned_by().
