Ilya Leoshkevich 3de55893f6 s390/bpf: Implement BPF_MOV | BPF_X with sign-extension
Implement the cpuv4 register-to-register move with sign extension. It
is distinguished from the normal moves by non-zero values in
insn->off, which determine the source size. s390x has instructions to
deal with all of them: lbr, lhr, lgbr, lghr and lgfr.
