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.
