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