Upon first call, the list of arguments which might need initialization init_list is freed to indicate that they have been processed. For instructions without an rvalue predicate, gen_inst_init_args() isn't called and init_list will never be freed. Free init_list from free_instruction() if it hasn't already been freed. A comment in free_instruction is also updated.
