Martin KaFai Lau 54ea6079b7 bpf: selftest: A bpf prog that has a 32bit scalar spill 
It is a simplified example that can trigger a 32bit scalar spill.
The const scalar is refilled and added to a skb->data later.
Since the reg state of the 32bit scalar spill is not saved now,
adding the refilled reg to skb->data and then comparing it with
skb->data_end cannot verify the skb->data access.

With the earlier verifier patch and the llvm patch [1].  The verifier
can correctly verify the bpf prog.

Here is the snippet of the verifier log that leads to verifier conclusion
that the packet data is unsafe to read.  The log is from the kerne
without the previous verifier patch to save the <8-byte scalar spill.
