Auto merge of #93014 - Kobzol:revert-92103-stable-hash-skip-zero-bytes, r=the8472
Revert "Do not hash leading zero bytes of i64 numbers in Sip128 hasher"

Reverts rust-lang/rust#92103. It had a (in retrospect, obvious) correctness problem where changing the order of two adjacent values would produce identical hashes, which is problematic in stable hashing (see [this comment](https://github.com/rust-lang/rust/pull/92103#issuecomment-1014625442)).

I'll try to send the PR again with a fix for this issue.
