rustc_lint: Prevent triplication of various lints Prevent triplication of various lints. The triplication happens because we run the same lint three times (or less in some cases): * In `BuiltinCombinedPreExpansionLintPass` * In `BuiltinCombinedEarlyLintPass` * In `shallow_lint_levels_on()` Only run the lints one time by checking the `lint_added_lints` bool. Set your GitHub diff setting to ignore whitespaces changes when reviewing this PR, since I had to enclose a block inside an if. Closes #73301 (I found this while exploring the code related to [this](https://github.com/rust-lang/rust/pull/119251#discussion_r1435677330) comment.)
