A lot of this is more boring "remove unused header", plus some other minor cleanups. I think the most significant changes were: - yaml_test_helpers.cpp is doing a switch on an unsigned int, comparing to enum values. - [bugprone-switch-missing-default-case](https://clang.llvm.org/extra/clang-tidy/checks/bugprone/switch-missing-default-case.html) is unhappy with EnumBase, but correctly identified yaml_test_helpers.cpp, so I'm opting to address it rather than disabling it even though it needs NOLINT in several locations as a result, in addition to what I think are some low-value `default` cases. I'd be fine going the other way with this too and disabling it globally (I could see it being noisier in the explorer). - MarkInitializerFor swaps the argument names between the .h and .cpp. I think the .cpp had the order as intended. - There's a new-ish [performance-enum-size](https://clang.llvm.org/extra/clang-tidy/checks/performance/enum-size.html) which I'm basically treating as "add int8_t to enums". My main motivation here is to just clean up as many of these as I can so that I stop seeing them in vscode.
