Add ARMv8/AArch64 Crypto Extension implementation of AES
* cipher/Makefile.am: Add 'rijndael-armv-aarch64-ce.S'.
* cipher/rijndael-armv8-aarch64-ce.S: New.
* cipher/rijndael-internal.h (USE_ARM_CE): Enable for ARMv8/AArch64.
* configure.ac: Add 'rijndael-armv-aarch64-ce.lo' and
'rijndael-armv8-ce.lo' for ARMv8/AArch64.
