Bug report

As discussed in https://github.com/phpstan/phpstan-src/pull/597, the PDOStatement::fetchAll doesn't match the new signature in PHP 8.

Code snippet that reproduces the problem

https://phpstan.org/r/7db12f52-a9a5-4fa2-a04f-caab9143bf9f

<?php declare(strict_types = 1);

(new PDOStatement)->fetchAll(
	PDO::FETCH_CLASS,
	StdClass::class,
	[new StdClass]
);

Expected output

No error!

Did PHPStan help you today? Did it make you happy in any way?

This is an awesome piece of software! I'm really putting a lot of work getting one of my biggest code bases to adhere to level 8 so bugs will be picked up quicker in the future! Thanks a bunch :)
