S390: Add z13 memmem ifunc variant.
The new vector variant of memmem is using the common code implementation, but instead of calling the default mem* functions, the vector variants are called. ChangeLog: * sysdeps/s390/Makefile (sysdep_routines): Add memmem variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Add ifunc variants for memmem. * sysdeps/s390/ifunc-memmem.h: New file. * sysdeps/s390/memmem.c: Likewise. * sysdeps/s390/memmem-c.c: Likewise. * sysdeps/s390/memmem-vx.c: Likewise.
