Makes a function associated with another instance of a script (the one representing its old version). This way the function still may access its own text.
function LinkToOldScript(old_info_node, old_script, report_array) {
    if (old_info_node.live_shared_function_infos) {
      old_info_node.live_shared_function_infos.
          forEach(function (info) {
            %LiveEditFunctionSetScript(info.info, old_script);
          });

      report_array.push( { name: old_info_node.info.function_name } );
    } else {
      report_array.push(
          { name: old_info_node.info.function_name, not_found: true } );
    }
  }
