This adds support for lint groups to the compiler. Lint groups are a way of grouping a number of lints together under one name. For example, this also defines a default lint for naming conventions, named `bad_style`. Writing `#[allow(bad_style)]` is equivalent to writing `#[allow(non_camel_case_types, non_snake_case, non_uppercase_statics)]`. These lint groups can also be defined as a compiler plugin using the new `Registry::register_lint_group` method. This also adds two built-in lint groups, `bad_style` and `unused`. The contents of these groups can be seen by running `rustc -W help`.
