src: clean up PER_ISOLATE_STRING_PROPERTIES, v2
Remove strings from the PER_ISOLATE_STRING_PROPERTIES list that are only used once during initialization. It's less expensive to simply create them when needed than turn them into v8::Eternal instances. PR-URL: #8207 Reviewed-By: Franziska Hinkelmann <franziska.hinkelmann@gmail.com> Reviewed-By: James M Snell <jasnell@gmail.com>
