Log Message

Add privileged registers for s390x

The Linux kernel and thus the linux-kernel target needs access to S390x's
privileged registers. Define new features and prepare s390-tdep.* to use
them in new Linux kernel code.

gdb/ChangeLog:

* features/s390-cr.xml: New file.
* features/s390x-cr-linux64.xml: New file
* features/s390x-vxcr-linux64.xml: New file
* features/Makefile: Add s390x-cr-linux64-expedite and
s390x-vxcr-linux64-expedite
(WICH): Add s390x-cr-linux64.xml and s390x-vxcr-linux64.xml
(XMLTOC): Add s390x-cr-linux64.xml and s390x-vxcr-linux64.xml
* features/s390x-cr-linux64.c: Generated.
* features/s390x-vxcr-linux64.c: Generated.
* regformats/s390x-cr-linux64.dat: Generated.
* regformats/s390x-vxcr-linux64.dat: Generated.
* s390-tdep.h: Define regnums for control registers.
(S390_NUM_REGS): Adjust.
* s390-tdep.c: (s390_dwarf_regmat): Add control registers.
