ad1c23c993 Maintain chain of derived obligations 
When evaluating the derived obligations from super traits, maintain a
reference to the original obligation in order to give more actionable
context in the output.

fda3378e3f introduce negative_impls feature gate and document 
They used to be covered by `optin_builtin_traits` but negative impls
are now applicable to all traits, not just auto traits.

This also adds docs in the unstable book for the current state of auto traits.

8119d0853d Track all predicates in errors, not just trait obligations 
Surface associated type projection bounds that could not be fulfilled in
E0599 errors. Always present the list of unfulfilled trait bounds,
regardless of whether we're pointing at the ADT or trait that didn't
satisfy it.
