This patch introduces the new arch13 ifunc variant for strstr.
For needles longer than 9 charachters 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 strstr-arch13.
* sysdeps/s390/ifunc-strstr.h (HAVE_STRSTR_ARCH13, STRSTR_ARCH13,
STRSTR_Z13_ONLY_USED_AS_FALLBACK, HAVE_STRSTR_IFUNC_AND_ARCH13_SUPPORT):
New defines.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add ifunc variant for arch13 strstr.
* sysdeps/s390/strstr-arch13.S: New file.
* sysdeps/s390/strstr-vx.c: Omit GI symbol for z13 strstr ifunc variant
if it is only used as fallback.
* sysdeps/s390/strstr.c (strstr): Add arch13 variant in ifunc selector.

This patch introduces the new arch13 ifunc variant for memmove.
For the forward or non-overlapping case it is just using memcpy.
For the backward case it relies on the new instruction mvcrl.
The instruction copies up to 256 bytes at once.
In case of an overlap, it copies the bytes like copying them
one by one starting from right to left.
ChangeLog:
* sysdeps/s390/ifunc-memcpy.h (HAVE_MEMMOVE_ARCH13, MEMMOVE_ARCH13
HAVE_MEMMOVE_IFUNC_AND_ARCH13_SUPPORT): New defines.
* sysdeps/s390/memcpy-z900.S: Add arch13 memmove implementation.
* sysdeps/s390/memmove.c (memmove): Add arch13 variant in
ifunc selector.
* sysdeps/s390/multiarch/ifunc-impl-list.c
(__libc_ifunc_impl_list): Add ifunc variant for arch13 memmove.
* sysdeps/s390/multiarch/ifunc-resolve.h (S390_STFLE_BITS_ARCH13_MIE3,
S390_IS_ARCH13_MIE3): New defines.

Add two configure checks which detect if arch13 is supported
by the assembler at all - by explicitely setting the machine -
and if it is supported with default settings.
ChangeLog:
* config.h.in (HAVE_S390_MIN_ARCH13_ZARCH_ASM_SUPPORT,
HAVE_S390_ARCH13_ASM_SUPPORT): New undefine.
* sysdeps/s390/configure.ac: Add checks for arch13 support.
* sysdeps/s390/configure: Regenerated.

The new hwcap values indicate support for:
-"Vector-Enhancements Facility 2" (tag "vxe2", hwcap 2^15)
-"Vector-Packed-Decimal-Enhancement Facility" (tag "vxp", hwcap 2^16)
-"Enhanced-Sort Facility" (tag "sort", hwcap 2^17)
-"Deflate-Conversion Facility" (tag "dflt", hwcap 2^18)
The vxe2 hwcap is also marked as important hwcap.
ChangeLog:
* sysdeps/s390/dl-procinfo.c (_dl_s390_cap_flags):
Add vxe2, vxp, dflt, sort flags.
* sysdeps/s390/dl-procinfo.h: Add HWCAP_S390_VXRS_EXT2,
HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT, HWCAP_S390_DFLT
capabilities.
(HWCAP_IMPORTANT): Add HWCAP_S390_VXRS_EXT2.
* sysdeps/unix/sysv/linux/s390/bits/hwcap.h
(HWCAP_S390_VXRS_EXT2, HWCAP_S390_VXRS_PDE, HWCAP_S390_SORT,
HWCAP_S390_DFLT): Define.

This patch adds vx and vxe as important hwcaps
which allows one to provide shared libraries
tuned for platforms with non-vx/-vxe, vx or vxe.
ChangeLog:
* sysdeps/s390/dl-procinfo.h (HWCAP_IMPORTANT):
Add HWCAP_S390_VX and HWCAP_S390_VXE.

The stub implementations are turned into compat symbols.
Linux actually has two reserved system call numbers (for getpmsg
and putpmsg), but these system calls have never been implemented,
and there are no plans to implement them, so this patch replaces
the wrappers with the generic stubs.
According to <https://bugzilla.redhat.com/show_bug.cgi?id=436349>,
the presence of the XSI STREAMS declarations is a minor portability
hazard because they are not actually implemented.
This commit does not change the TIRPC support code in
sunrpc/rpc_svcout.c. It uses additional XTI functionality and
therefore never worked with glibc.

The recent commit 81a14439417552324ec6ca71f65ddf8e7cdd51c7
has introduced __wcscpy, __GI___wcscpy and the weak alias wcscpy.
This patch also introduces those symbols if glibc is build
with CFLAGS="-march=z13" where the ifunc is omitted.
ChangeLog:
* sysdeps/s390/wcscpy-vx.S: Add strong aliases to
__wcscpy, __GI___wcscpy and weak alias to wcscpy.

This patch rewrites wcscat using wcslen and wcscpy. This is similar to
the optimization done on strcat by 6e46de42fe.
The strcpy changes are mainly to add the internal alias to avoid PLT
calls.
Checked on x86_64-linux-gnu and a build against the affected
architectures.

This patch fixes -Wimplicit-fallthrough warnings in system-specific

This patch makes further coding style fixes where code was breaking
lines after an operator, contrary to the GNU Coding Standards. As

The ifunc macros s390_vx_libc* are no longer used and
can be removed as all users are now relying on
s390_libc_ifunc_expr.
The same applies to s390_libc_ifunc. The macro
s390_libc_ifunc_init is now renamed to
s390_libc_ifunc_expr_stfle_init and the users are
adjusted accordingly.

The ifunc handling for various __gconv_transform_* functions
which are using IFUNC on s390x are adjusted in order to omit ifunc
if the minimum architecture level already supports newer CPUs by default.
Instead those functions are just an alias to the vector variants.
Furthermore the ifunc-macro s390_libc_ifunc_expr is now used instead of
s390_vx_libc_ifunc.

The ifunc handling for strspn 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.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove strspn variants.
* sysdeps/s390/Makefile (sysdep_routines): Add strspn variants.

The ifunc handling for strcmp 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 clst instruction
are now moved to the unified strcmp-z900.S file which can be used for
31/64bit. The s390-32/s390-64 files multiarch/strcmp.c and strcmp.S
are deleted.
ChangeLog:
* sysdeps/s390/multiarch/Makefile
(sysdep_routines): Remove strcmp variants.
