Auto merge of #89323 - estebank:derive-binop, r=petrochenkov
Consider unfulfilled obligations in binop errors When encountering a binop where the types would have been accepted, if all the predicates had been fulfilled, include information about the predicates and suggest appropriate `#[derive]`s if possible. Fix #84515.
