Initialize orig_args with nullptr and allocate it if it hasn't yet been allocated, either during construction or during fix_fields(), depending on use. THe SQL layer calls print() on conditions as a way of validating that they're correct, but in the case of Item_func_group_concat, this crashed because orig_args was not allocated by that point for the test case included in this commit.
