Since interpretation of regs->[sb]p should be done in the context of regs->ss, and we have code actually doing that (see arch/x86/lib/insn-eval.c for instance), complete the job by also pushing ss. This ensures that anybody who does do look at regs->ss doesn't mysteriously malfunction, avoiding much future pain.
