[AArch64] Add ifunc support for Ares
Add Ares to the midr_el0 list and support ifunc dispatch. Since Ares supports 2 128-bit loads/stores, use Neon registers for memcpy by selecting __memcpy_falkor by default (we should rename this to __memcpy_simd or similar). * manual/tunables.texi (glibc.cpu.name): Add ares tunable. * sysdeps/aarch64/multiarch/memcpy.c (__libc_memcpy): Use __memcpy_falkor for ares. * sysdeps/unix/sysv/linux/aarch64/cpu-features.h (IS_ARES): Add new define. * sysdeps/unix/sysv/linux/aarch64/cpu-features.c (cpu_list): Add ares cpu. (cherry picked from commit 02f440c1ef5d5d79552a524065aa3e2fabe469b9)
