David Benjamin 40c24d74de Don't use __ARMEL__/__ARMEB__ in aarch64 assembly
GCC's __ARMEL__ and __ARMEB__ defines denote little- and big-endian arm,
respectively. They are not defined on aarch64, which instead use
__AARCH64EL__ and __AARCH64EB__.

However, OpenSSL's assembly originally used the 32-bit defines on both
platforms and even define __ARMEL__ and __ARMEB__ in arm_arch.h. This is
less portable and can even interfere with other headers, which use
__ARMEL__ to detect little-endian arm.

Over time, the aarch64 assembly has switched to the correct defines,
such as in 32bbb62ea6. This commit
finishes the job: poly1305-armv8.pl needed a fix and the dual-arch
armx.pl files get one more transform to convert from 32-bit to 64-bit.

(There is an even more official endianness detector, __ARM_BIG_ENDIAN in
the Arm C Language Extensions. But I've stuck with the GCC ones here as
that would be a larger change.)
