Similar to how the alignment is already checked, this adds a check for null pointer dereferences in debug mode. It is implemented similarly to the alignment check as a MirPass. This is related to a 2025H1 project goal for better UB checks in debug mode: https://github.com/rust-lang/rust-project-goals/pull/177.
