S390: Refactor strcmp ifunc handling.
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. * sysdeps/s390/Makefile (sysdep_routines): Add strcmp variants. * sysdeps/s390/multiarch/ifunc-impl-list.c (__libc_ifunc_impl_list): Refactor ifunc handling for strcmp. * sysdeps/s390/multiarch/strcmp-vx.S: Move to ... * sysdeps/s390/strcmp-vx.S: ... here and adjust ifunc handling. * sysdeps/s390/multiarch/strcmp.c: Move to ... * sysdeps/s390/strcmp.c: ... here and adjust ifunc handling. * sysdeps/s390/ifunc-strcmp.h: New file. * sysdeps/s390/s390-64/strcmp.S: Move to ... * sysdeps/s390/strcmp-z900.S: ... here and adjust to be usable for 31/64bit and ifunc handling. * sysdeps/s390/s390-32/multiarch/strcmp.c: Delete file. * sysdeps/s390/s390-64/multiarch/strcmp.c: Likewise. * sysdeps/s390/s390-32/strcmp.S: Likewise.
