With the above suggestion it should now yield an "unexpected token" error.
If you wish to get "unavailable in V8" error, you need to pass ParseForAllFeatures == true to MatchOperandParserImpl so that parsePrefetchTag is called in V8 mode too. This will probably result in many test changes and should be done separately.
