S390: Refactor memcmp ifunc handling.
This patch moves all ifunc variants for memcmp to sysdeps/s390/memcmp-z900.S. The configure-check/preprocessor logic in sysdeps/s390/ifunc-memcmp.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-memcmp.h: New File. * sysdeps/s390/memcmp.S: Move to ... * sysdeps/s390/memcmp-z900.S ... here. Move implementations from memcmp-s390x.s to here. * sysdeps/s390/multiarch/memcmp-s390x.S: Delete File. * sysdeps/s390/multiarch/Makefile (sysdep_routines): Remove memcmp variants. * sysdeps/s390/Makefile (sysdep_routines): Add memcmp variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Adjust ifunc variants for memcmp. * sysdeps/s390/multiarch/memcmp.c: Move ifunc resolver to ... * sysdeps/s390/memcmp.c: ... here. Adjust ifunc variants for memcmp.
