crypto/md5: add assembly implementation on arm64
This change improves the performance of the block
function used within crypto/md5 on arm64. The following
improvement was seen:
name old time/op new time/op delta
Hash8Bytes 1.62µs ± 0% 0.85µs ± 0% -47.83% (p=0.000 n=8+10)
Hash1K 8.82µs ± 0% 7.10µs ± 3% -19.52% (p=0.000 n=10+10)
Hash8K 59.5µs ± 2% 50.2µs ± 0% -15.63% (p=0.000 n=9+10)
Hash8BytesUnaligned 1.63µs ± 0% 0.85µs ± 0% -47.92% (p=0.000 n=9+10)
