Changes to the builder certainly need new tests in ConstantArrayTypeBuilderTest.

I'd thought about this method that it should be set once after creation and not before every setOffsetValueType call. It should change the behaviour for all the calls, not just for the next one. Instead of this logic, this method should switch a bool property so that the computation of nextAutoIndexes changes based on that.

return;
}
$this->nextAutoIndexes = [0];
}

I'd prefer if the conditions contained the whole yield from call instead of concatenating the path dynamically like this. It will make the path clickable in IDE.
