421749d693 S390: Add arch13 memmem ifunc variant.
This patch introduces the new arch13 ifunc variant for memmem.
For needles longer than 9 bytes it is relying on the common-code
implementation.  For shorter needles it is using the new vstrs instruction
which is able to search a substring within a vector register.

ChangeLog:

	* sysdeps/s390/Makefile (sysdep_routines): Add memmem-arch13.
	* sysdeps/s390/ifunc-memmem.h (HAVE_MEMMEM_ARCH13, MEMMEM_ARCH13,
	MEMMEM_Z13_ONLY_USED_AS_FALLBACK, HAVE_MEMMEM_IFUNC_AND_ARCH13_SUPPORT):
	New defines.
	* sysdeps/s390/memmem-arch13.S: New file.
	* sysdeps/s390/memmem-vx.c: Omit GI symbol for z13 memmem ifunc variant
	if it is only used as fallback.
	* sysdeps/s390/memmem.c (memmem): Add arch13 variant in ifunc selector.
	* sysdeps/s390/multiarch/ifunc-impl-list.c
	(__libc_ifunc_impl_list): Add ifunc variant for arch13 memmem.

d2a7436c1c S390: Refactor wmemset ifunc handling.
The ifunc handling for wmemset is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.
Glibc internal calls will use the "newer" ifunc variant.

c7e7cd266e S390: Refactor wcsnlen ifunc handling.
The ifunc handling for wcsnlen is adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Unfortunately the c ifunc variant can't be omitted at all as it is used
by the z13 ifunc variant as fallback if the pointers are not 4-byte aligned.
Glibc internal calls will use the "newer" ifunc variant.

ChangeLog:

	* sysdeps/s390/multiarch/Makefile
	(sysdep_routines): Remove wcsnlen variants.
	* sysdeps/s390/Makefile (sysdep_routines): Add wcsnlen variants.

914a4e0557 S390: Refactor strcpy ifunc handling.
The ifunc handling for strcpy is adjusted in order to omit ifunc
variants if those will never be used as the minimum architecture level
already supports newer CPUs by default.
Glibc internal calls will then also use the "newer" ifunc variant.

Note: The fallback s390-32/s390-64 ifunc variants with mvst instruction
are now moved to the unified strcpy-z900.S file which can be used for
31/64bit. The s390-32/s390-64 files multiarch/strcpy.c and strcpy.S
are deleted.

cdd927d98c S390: Add z13 memmove ifunc variant.
This patch introduces a z13 specific ifunc variant for memmove.
As the common code implementation, it checks if we can copy from
the beginning to the end - with z196 memcpy implementation - or
if we have to copy from the end to the beginning.
The latter case is done by using vector load/store instructions.

If vector instructions are not available, the common-code is
used as fallback.  Therefore it is implemented in memmove-c with
a different name.
Furthermore the ifunc logic decides if we need the common-code
implementation at all.  If vector instructions are supported
due to the minimum architecture level set we can skip the
common-code ifunc variant.

ChangeLog:

	* sysdeps/s390/Makefile (sysdep_routines): Add memmove-c.
	* sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_IFUNC,

18eb862d45 S390: Refactor memcpy/mempcpy ifunc handling.
This patch moves all ifunc variants for memcpy/mempcpy
to sysdeps/s390/memcpy-z900.S. The configure-check/preprocessor logic
in sysdeps/s390/ifunc-memcpy.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.

2bfdaeddaa Rename cppflags-iterator.mk to libof-iterator.mk, remove extra-modules.mk.
cppflags-iterator.mk no longer has anything to do with CPPFLAGS; all
it does is set libof-$(foo) for a list of files.  extra-modules.mk
does the same thing, but with a different input variable, and doesn't
let the caller control the module.  Therefore, this patch gives
cppflags-iterator.mk a better name, removes extra-modules.mk, and
updates all uses of both.

	* extra-modules.mk: Delete file.
	* cppflags-iterator.mk: Rename to ...
	* libof-iterator.mk: ...this.  Adjust comments.
