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.
