selftests/bpf: Add tests for raw_tp null handling
[ Upstream commit 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.
