selftests/bpf: Add tests with stack ptr register in conditional jmp
commit 5ffb537e416ee22dbfb3d552102e50da33fec7f6 upstream.
Add two tests:
- one test has 'rX <op> r10' where rX is not r10, and
- another test has 'rX <op> rY' where rX and rY are not r10
but there is an early insn 'rX = r10'.
Without previous verifier change, both tests will fail.
