Auto merge of #69332 - nnethercote:revert-u8to64_le-changes, r=michaelwoerister
Revert `u8to64_le` changes from #68914. `SipHasher128`'s `u8to64_le` function was simplified in #68914. Unfortunately, the new version is slower, because it introduces `memcpy` calls with non-statically-known lengths. This commit reverts the change, and adds an explanatory comment (which is also added to `libcore/hash/sip.rs`). This barely affects `SipHasher128`'s speed because it doesn't use `u8to64_le` much, but it does result in `SipHasher128` once again being consistent with `libcore/hash/sip.rs`. r? @michaelwoerister
