Add tests to ensure that arguments are correctly marked based on their
specified positions, and whether they get marked correctly as maybe
null. For modules, all tracepoint parameters should be marked
PTR_MAYBE_NULL by default.

selftests/bpf: Add tests for raw_tp null handling2024-11-04T19:37:36ZKumar Kartikeya Dwivedi2024-11-04T17:19:59Zurn:sha1:d798ce3f4cab1b0d886b19ec5cc8e6b3d7e35081
Ensure that trusted PTR_TO_BTF_ID accesses perform PROBE_MEM handling in
raw_tp program. Without the previous fix, this selftest crashes the
kernel due to a NULL-pointer dereference. Also ensure that dead code
elimination does not kick in for checks on the pointer.
