Add Niagara-4 optimized memset/bzero implementation.
* sysdeps/sparc/sparc64/multiarch/memset-niagara4.S: New file.
* sysdeps/sparc/sparc32/sparcv9/multiarch/memset-niagara4.S: New
file.
* sysdeps/sparc/sparc64/multiarch/Makefile: Add to
sysdep_routines.
* sysdeps/sparc/sparc32/sparcv9/multiarch/Makefile: Likewise.
* sysdeps/sparc/sparc64/multiarch/memset.S: Use Niagara-4 memset
and bzero when HWCAP_SPARC_CRYPTO is present.
