selftests/bpf: Add test coverage for reg_set_min_max handling
Add a test case for the jmp32/k fix to ensure selftests have coverage.
Before fix:
# ./vmtest.sh -- ./test_progs -t verifier_or_jmp32_k
[...]
./test_progs -t verifier_or_jmp32_k
tester_init:PASS:tester_log_buf 0 nsec
process_subtest:PASS:obj_open_mem 0 nsec
process_subtest:PASS:specs_alloc 0 nsec
run_subtest:PASS:obj_open_mem 0 nsec
run_subtest:FAIL:unexpected_load_success unexpected success: 0
#492/1 verifier_or_jmp32_k/or_jmp32_k: bit ops + branch on unknown value:FAIL
#492 verifier_or_jmp32_k:FAIL
Summary: 0/0 PASSED, 0 SKIPPED, 1 FAILED
After fix:
# ./vmtest.sh -- ./test_progs -t verifier_or_jmp32_k
[...]
./test_progs -t verifier_or_jmp32_k
#492/1 verifier_or_jmp32_k/or_jmp32_k: bit ops + branch on unknown value:OK
#492 verifier_or_jmp32_k:OK
Summary: 1/1 PASSED, 0 SKIPPED, 0 FAILED
