b151b513ba Insert null checks for pointer dereferences when debug assertions are enabled 
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.

851322b74d Refactor PointerFinder into a separate module 
This also parameterize the "excluded pointee types" and exposes a
general method for inserting checks on pointers.

This is a preparation for adding a NullCheck that makes use of the same
code.
