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.
