aarch64: Add AmpereComputing emag to tunable cpu list
Emag is a 64-bit CPU core released by AmpereComputing. Add its name to cpu list, and corresponding macro as utilities for later IFUNC dispatch. * manual/tunables.texi (Tunable glibc.cpu.name): Add emag. * sysdeps/unix/sysv/linux/aarch64/cpu-features.c (cpu_list): Add emag. * sysdeps/unix/sysv/linux/aarch64/cpu-features.h (IS_EMAG): New macro.
