selftests/bpf: BPF test_verifier selftests for bpf_loop inlining
A number of test cases for BPF selftests test_verifier to check how
bpf_loop inline transformation rewrites the BPF program. The following
cases are covered:
- happy path
- no-rewrite when flags is non-zero
- no-rewrite when callback is non-constant
- subprogno in insn_aux is updated correctly when dead sub-programs
are removed
- check that correct stack offsets are assigned for spilling of R6-R8
registers
