07be392807 S390: Implement bzero with memset. 
This patch removes the bzero s390 implementation with mvcle and
adds entry points for bzero in memset ifunc variants.
Therefore an ifunc resolver is implemented for bzero, too.

ChangeLog:

	* sysdeps/s390/s390-32/bzero.S: Delete file.
	* sysdeps/s390/s390-64/bzero.S: Likewise.
	* sysdeps/s390/Makefile (sysdep_routines): Add bzero.
	* sysdeps/s390/bzero.c: New file.
	* sysdeps/s390/memset-z900.S: Add bzero entry points.
	* sysdeps/s390/ifunc-memset.h: Add bzero function macros.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add bzero ifunc variants.

712a254a97 S390: Refactor memset ifunc handling. 
This patch moves all ifunc variants for memset
to sysdeps/s390/memset-z900.S. The configure-check/preprocessor logic
in sysdeps/s390/ifunc-memset.h decides if ifunc is needed at all
and which ifunc variants should be available.
E.g. if the compiler/assembler already supports z196 by default,
the older ifunc variants are not included.
If we only need the newest ifunc variant,
then we can skip ifunc at all.

Therefore the ifunc-resolvers and __libc_ifunc_impl_list are adjusted
in order to handle only the available ifunc variants.

ChangeLog:

	* sysdeps/s390/ifunc-memset.h: New File.
	* sysdeps/s390/memset.S: Move to ...
	* sysdeps/s390/memset-z900.S ... here.
	Move implementations from memset-s390x.s to here.
	* sysdeps/s390/multiarch/memset-s390x.S: Delete File.
	* sysdeps/s390/multiarch/Makefile (sysdep_routines):
	Remove memset variants.
	* sysdeps/s390/Makefile (sysdep_routines):
	Add memset variants.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Adjust ifunc variants for
	memset.
	* sysdeps/s390/multiarch/memset.c: Move ifunc resolver
	to ...
	* sysdeps/s390/memset.c: ... here.
	Adjust ifunc variants for memset.
