in a followup PR I would factor out the 2 $constantType instanceof ConstantIntegerType if-blocks of this method into the parent caller and do a proper integer range check instead, which will fix phpstan/phpstan#11558
I don't do it now to keep this PR simpler and the next one will also be easier to review
