[php-src] Issue #10985: PHP parser: operator precedence of `instanceof` vs `::` is weird

Issue: https://github.com/php/php-src/issues/10985 Author: mikkorantalainen ### Description The following code: ```php <?php $c = new stdClass(); assert($c instanceof (stdClass::class)); assert($c instanceof stdClass::class); echo "OK"; ``` Resulted in this output: ``` Parse error: syntax error, unexpected token "class", expecting variable or "$" in /path/to/test.php on line 4 [Process exited with code 255.] ``` But I expected this output instead: ``` OK ``` The code without extra parenthesis should do the same thing. It makes zero sense to have operator instanceof precedence higher than ::. ### PHP Version PHP 8.0.28 ### Operating System _No response_
