Rollup merge of #74516 - lcnr:min-specialization-ice, r=matthewjasper
do not try fetching the ancestors of errored trait impls

fixes #74483

While building the specialization graph, we use `tcx.all_impls` which discards impls with incorrect self types,
we do however call `trait_def.ancestors` with these impls which caused an ICE as they aren't part of the
specialization graph.
