This patch enables the command line options and provides the proper
macros for checking.

gcc/ChangeLog:

2019-04-02  Andreas Krebbel  <krebbel@linux.ibm.com>

	* common/config/s390/s390-common.c (processor_flags_table): New
	entry for arch13.
	* config.gcc: Support arch13 with the --with-arch= configure flag.
	* config/s390/driver-native.c (s390_host_detect_local_cpu):
	* config/s390/s390-opts.h (enum processor_type): Add PROCESSOR_ARCH13.
	* config/s390/s390.c (s390_get_sched_attrmask)
	(s390_get_unit_mask): Add PROCESSOR_ARCH13.
	* config/s390/s390.h (enum processor_flags): Add PF_VXE2 and PF_ARCH13.
	* config/s390/s390.md (TARGET_CPU_ARCH13, TARGET_CPU_ARCH13_P)
	(TARGET_CPU_VXE2, TARGET_CPU_VXE2_P, TARGET_ARCH13)
	(TARGET_ARCH13_P, TARGET_VXE2, TARGET_VXE2_P): New macro
	definitions.
	* config/s390/s390.opt: Support arch13 as processor type in
	command line options.
