Function safe_arch::crc32_u64

#[must_use]pub fn crc32_u64(crc: u64, v: u64) -> u64

This is supported with target feature sse4.2 only.

Accumulates the u64 into a running CRC32 value.

Note that, unlike with the other crc32 functions, the running CRC32 input and output is a u64 value in addition to the new value to accumulate being a u64.

assert_eq!(crc32_u64(u64::MAX, u64::MAX), 3080238136_u64);
