arch64: Add SIMD version of memcpy
Create a new memcpy implementation for targets with the NEON extension.
__memcpy_aarch64_simd has been tested on a range of modern
microarchitectures. It turned out to be faster than __memcpy_aarch64 on
all of them, with a performance improvement of 3-11% depending on the
platform.
