`AliasingSafe` is really about whether a pointer permits unsynchronized reads - either because the referent contains no `UnsafeCell`s or because the aliasing mode is `Exclusive`. Previously, `AliasingSafe` was not named consistent with this meaning, and was a function of a *pair* of types rather than of a single type. This commit fixes both oversights. While we're here, we also add `Read` bounds in some places, allowing us to simplify many safety comments.
