Function build_pointer_or_reference_di_node

fn build_pointer_or_reference_di_node<'ll, 'tcx>(
    cx: &CodegenCx<'ll, 'tcx>,
    ptr_type: Ty<'tcx>,
    pointee_type: Ty<'tcx>,
    unique_type_id: UniqueTypeId<'tcx>,
) -> DINodeCreationResult<'ll>

Creates debuginfo for built-in pointer-like things:

• ty::Ref
• ty::RawPtr
• ty::Adt in the case it’s Box

At some point we might want to remove the special handling of Box and treat it the same as other smart pointers (like Rc, Arc, …).
