b665d2d865 Adopt new SSE2NEON and reduce ARM-specific changes 
This patch updated SSE2NEON [1], which contains more functions
provided by Intel intrinsics, only implemented with NEON-based
counterparts to produce the exact semantics of the intrinsics.
Consequently, ARM-specific changes against CryptoNight_arm can
be reduced as well.
