2018-06-22Rollup merge of #51664 - jebrosen:pub_parse_methods2, r=Mark-Simulacrumkennytm-3/+3
make more libsyntax methods public Followup for #51502, which was sufficient only for the latest stable release of Rocket. The `master` branch uses a few more. I plan to reimplement the deleted method `parse_seq` in Rocket (see SergioBenitez/Rocket#666), rather than resurrecting it in libsyntax. r? @Mark-Simulacrum
2018-06-22Rollup merge of #51629 - topecongiro:multiple-semicolon-in-local-span, ↵kennytm-1/+1
r=petrochenkov Do not consume semicolon twice while parsing local statement The span for a `let` statement includes multiple semicolons. For example, ```rust let x = 2;;; // ^^^^^^^^^^^ The span for the above statement. ``` This PR fixes it. cc https://github.com/rust-lang-nursery/rustfmt/issues/2791.

2018-06-21Parse async fn header.Without Boats-103/+160
This is gated on edition 2018 & the `async_await` feature gate. The parser will accept `async fn` and `async unsafe fn` as fn items. Along the same lines as `const fn`, only `async unsafe fn` is permitted, not `unsafe async fn`.The parser will not accept `async` functions as trait methods. To do a little code clean up, four fields of the function type struct have been merged into the new `FnHeader` struct: constness, asyncness, unsafety, and ABI. Also, a small bug in HIR printing is fixed: it previously printed `const unsafe fn` as `unsafe const fn`, which is grammatically incorrect.

r=nikomatsakis Fix processing mod with multi-level path on Windows Fix error in [rustfmt](https://github.com/rust-lang-nursery/rustfmt/issues/1754) because libsyntax can not handle `mod` with multilevel path on Windows. Alternative is do almost same in https://github.com/rust-lang/rust/blob/master/src/libstd/sys/windows/fs.rs#L717 to allow work on paths with different separators, Ex. "\\\\?\\c:\\windows/temp"

Follow up to #51508, make parse_block public instead parse_block_expr This is an follow up to #51508 I mistakenly made parse_block_expr public instead of parse_block. This fixes this.
