aarch64: add HXT Phecda core memory operation ifuncs
Phecda is HXT semiconductor's CPU core, this patch adds memory operation ifuncs for it: sharing the same optimized implementation with Qualcomm's Falkor core. 2018-06-07 Minfeng Kang <minfeng.kang@hxt-semitech.com> Hongbo Zhang <hongbo.zhang@linaro.org> * sysdeps/aarch64/multiarch/memcpy.c (libc_ifunc): reuse __memcpy_falkor for phecda core. * sysdeps/aarch64/multiarch/memmove.c (libc_ifunc): reuse __memmove_falkor for phecda core. * sysdeps/aarch64/multiarch/memset.c (libc_ifunc): reuse __memset_falkor for phecda core. * sysdeps/unix/sysv/linux/aarch64/cpu-features.c: add MIDR entry for phecda core. * sysdeps/unix/sysv/linux/aarch64/cpu-features.h (IS_PHECDA): add macro to identify phecda core.
