    s390: Add record/replay support for arch13 instructions

    Enable recording most of the new "arch13" instructions on z/Architecture

    targets, except for the specialized-function-assist instructions:

      SORTL - sort lists

      DFLTCC - deflate conversion call

      KDSA - compute digital signature authentication

    gdb/ChangeLog:

            * s390-tdep.c (390_process_record): Handle new arch13 instructions

            except SORTL, DFLTCC, and KDSA.
