Aarch64 scrypt ASM #219

It would be beneficial with the introduction of arm64 Macs to add native scrypt code for aarch64.

Yes because building cpuminer 2.5.1 on Apple Silicon currently fails with:

Undefined symbols for architecture arm64:

This should make it rather easy to support Intel and Apple M1?
