Ilya Leoshkevich db7bee6538 s390/bpf: Fix optimizing out zero-extensions ... Currently the JIT completely removes things like `reg32 += 0`, however, the BPF_ALU semantics requires the target register to be zero-extended in such cases. Fix by optimizing out only the arithmetic operation, but not the subsequent zero-extension.
