rustdoc: Don't generate blanket impls when running --show-coverage `get_blanket_impls` is the slowest part of rustdoc, and the coverage pass completely ignores blanket impls. This stops running it at all, and also removes some unnecessary checks in `calculate_doc_coverage` that ignored the impl anyway. We don't currently measure --show-coverage in perf.rlo, but I tested this locally on cargo and it brought the time down from 2.9 to 1.6 seconds. This also adds back a commented-out test; Rustdoc has been able to deal with `impl trait` for almost a year now. r? `@GuillaumeGomez`
