2019-11-27Rollup merge of #66798 - bwignall:typo, r=varkorTyler Mandry-3/+3
Fix spelling typos Should be non-semantic. Uses https://en.wikipedia.org/wiki/Wikipedia:Lists_of_common_misspellings/For_machines to find likely typos.
2019-11-27Rollup merge of #66718 - VirrageS:use_comma, r=CentrilTyler Mandry-70/+67
Refactor `parse_enum_item` to use `parse_delim_comma_seq` Followup after https://github.com/rust-lang/rust/pull/66641 Some errors got more verbose but I think they make sense with the help message.

Ast address-of This is the parts of #64588 that don't affect MIR. If an address-of expression makes it to MIR lowering we error and lower to the best currently expressible approximation to limit further errors. r? @Centril

*Syntactically* permit visibilities on trait items & enum variants Fixes #65041 Suppose we have `$vis trait_item` or `$vis enum_variant` and `$vis` is a `:vis` macro fragment. Before this PR, this would fail to parse. This is now instead allowed as per language team consensus in https://github.com/rust-lang/rust/issues/65041#issuecomment-538105286. (See added tests for elaboration.) Moreover, we now also permit visibility modifiers on trait items & enum variants *syntactically* but reject them with semantic checks (in `ast_validation`): ```rust #[cfg(FALSE)] trait Foo { pub fn bar(); } // OK #[cfg(FALSE)] enum E { pub U } // OK ```

The previous commit removes the use of this, and now we cleanup.

2019-11-15Rollup merge of #66197 - Centril:transparent-ast, r=varkorTyler Mandry-48/+13
Push `ast::{ItemKind, ImplItemKind}::OpaqueTy` hack down into lowering We currently have a hack in the form of `ast::{ItemKind, ImplItemKind}::OpaqueTy` which is constructed literally when you write `type Alias = impl Trait;` but not e.g. `type Alias = Vec<impl Trait>;`. Per https://github.com/rust-lang/rfcs/pull/2515, this needs to change to allow `impl Trait` in nested positions. This PR achieves this change for the syntactic aspect but not the semantic one, which will require changes in lowering and def collection. In the interim, `TyKind::opaque_top_hack` is introduced to avoid knock-on changes in lowering, collection, and resolve. These hacks can then be removed and fixed one by one until the desired semantics are supported. r? @varkor
