The change looks good to me. At cursory glance I don't see other points in this pass that might require similar change.

I have a nit about the test: for IR to IR passes it is a general practice to run `opt -passes=<the-pass>` and verify the output. But all our tests for CORE seem to follow a different pattern, there is even no way to request `BPFAbstractMemberAccess` from `opt`, a change in the `BPFPassRegistry.def` is needed for that. So this is a moot point.
