Function build_unsafe_binder_type_di_node 

fn build_unsafe_binder_type_di_node<'ll, 'tcx>(
    cx: &GenericCx<'ll, FullCx<'ll, 'tcx>>,
    binder_type: Ty<'tcx>,
    unique_type_id: UniqueTypeId<'tcx>,
) -> DINodeCreationResult<'ll>

Creates the debuginfo node for unsafe<'a> T binder types.

We treat an unsafe binder like a struct with a single field named inner rather than delegating to the inner type’s DI node directly. This way the debugger shows the binder’s own type name, and the wrapped value is still accessible through the inner field.
