s390x : misc cleanups

- Remove fixs390 regarding storing the instruction address in the
  IP_AT_SYSCALL slot in the guest state. I'm not sure this is used
  but it certainly makes sense.

- Remove fixs390 in function s390_irgen_XONC. This was missed in
  VEX r2113.

Partial fix for #271501. (Florian Krohm, britzel@acm.org)
