2018-07-28Auto merge of #52355 - pietroalbini:zfeature, r=eddybbors-0/+5
Add the -Zcrate-attr=foo unstable rustc option This PR adds a new unstable option to `rustc`: `-Zcrate-attr=foo`. The option can be used to inject crate-level attributes from the CLI, and it's meant to be used by tools like Crater that needs to add their own attributes to a crate without changing the source code. The exact reason I need this is to implement "edition runs" in Crater: we need to add the preview feature flag to every crate, and editing the crates' source code on the fly might produce unexpected results, while a compiler flag is more reliable. cc https://github.com/rust-lang-nursery/crater/issues/282 @Mark-Simulacrum
2018-07-28Rollup merge of #52703 - ljedrz:vec_improvements, r=nikomatsakiskennytm-5/+4
Improve a few vectors - calculate capacity or build from iterators Collecting from iterators improves readability and tailoring vector capacities should be beneficial in terms of performance.

2018-06-28Auto merge of #50997 - michaelwoerister:pre-analyze-filemaps, r=Mark-Simulacrumbors-81/+489
Make FileMap::{lines, multibyte_chars, non_narrow_chars} non-mutable. This PR removes most of the interior mutability from `FileMap`, which should be beneficial, especially in a multithreaded setting. This is achieved by initializing the state in question when the filemap is constructed instead of during lexing. Hopefully this doesn't degrade performance. cc @wesleywiser
2018-06-28Fix FileMap::line_begin_pos().Michael Woerister-5/+3
The method relied on the FileMap still being under construction in order for it to do what the name promises. It's now independent of the current state.

Add existential type definitions Note: this does not allow creating named existential types, it just desugars `impl Trait` to a less (but still very) hacky version of actual `existential type` items. r? @nikomatsakis

Implement edition hygiene for keywords Determine "keywordness" of an identifier in its hygienic context. cc https://github.com/rust-lang/rust/pull/49611 I've resurrected `proc` as an Edition-2015-only keyword for testing purposes, but it should probably be buried again. EDIT: `proc` is removed again.

Streamline `StringReader::bump` These patches make `bump` smaller and nicer. They speed up most runs for coercions and tuple-stress by 1--3%.
