The implicit return statement is added within cp/decl.c:finish_function:

      if (DECL_MAIN_P (current_function_decl))
        {
          /* Make it so that `main' always returns 0 by default.  */
#if VMS_TARGET
          finish_return_stmt (integer_one_node);
#else
          finish_return_stmt (integer_zero_node);
#endif
        }
