Fix #16525: ObjectCode freed wrongly because of lack of info header check 

`checkUnload` currently doesn't check the info header of static objects.
Thus, it may free an `ObjectCode` struct wrongly even if there's still a
live static object whose info header lies in a mapped section of that
`ObjectCode`. This fixes the issue by adding an appropriate check.
