	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. r? `@the8472`

2020-09-30	Stable hashing: add comments and tests concerning platform-independence	Tyson Nottingham	-6/+19
	SipHasher128 implements short_write in an endian-independent way, yet its write_xxx Hasher trait methods undo this endian-independence by byte swapping the integer inputs on big-endian hardware. StableHasher then adds endian-independence back by also byte-swapping on big-endian hardware prior to invoking SipHasher128. This double swap may have the appearance of being a no-op, but is in fact by design. In particular, we really do want SipHasher128 to be platform-dependent, in order to be consistent with the libstd SipHasher. Try to clarify this intent. Also, add and update a couple of unit tests.
