Merge `TraitItem` & `ImplItem into `AssocItem` In this PR we: - Merge `{Trait,Impl}Item{Kind?}` into `AssocItem{Kind?}` as discussed in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. - This is done by using the cover grammar of both forms. - In particular, it requires that we syntactically allow (under `#[cfg(FALSE)]`): - `default`ness on `trait` items, - `impl` items without a body / definition (`const`, `type`, and `fn`), - and associated `type`s in `impl`s with bounds, e.g., `type Foo: Ord;`. - The syntactic restrictions are replaced by semantic ones in `ast_validation`. - Move syntactic restrictions around C-variadic parameters from the parser into `ast_validation`: - `fn`s in all contexts now syntactically allow `...`, - `...` can occur anywhere in the list syntactically (`fn foo(..., x: usize) {}`), - and `...` can be the sole parameter (`fn foo(...) {}`. r? @petrochenkov

2019-11-06Make doc comments cheaper with `AttrKind`.Nicholas Nethercote-8/+10
`AttrKind` is a new type with two variants, `Normal` and `DocComment`. It's a big performance win (over 10% in some cases) because `DocComment` lets doc comments (which are common) be represented very cheaply. `Attribute` gets some new helper methods to ease the transition: - `has_name()`: check if the attribute name matches a single `Symbol`; for `DocComment` variants it succeeds if the symbol is `sym::doc`. - `is_doc_comment()`: check if it has a `DocComment` kind. - `{get,unwrap}_normal_item()`: extract the item from a `Normal` variant; panic otherwise. Fixes #60935.
2019-11-06Remove unnecessary `Deref` impl for `Attribute`.Nicholas Nethercote-4/+4
This kind of thing just makes the code harder to read.

And make it more uniform with other macros. By merging placeholders for future derives' outputs into the derive container's output fragment early.
