Make UnsafeCell doc easier to follow
remove italic as per @GuillaumeGomez suggestion
This is propagated from rust-lang/prev.rust-lang.org#1062.
based on @nikomatsakis texthg
These change from release to release and are impossible to get right, since they are generated by Make magic.
(Meanwhile, a couple of parse-fail tests are moved to UI tests so that the reader can see the new output, and an existing UI test is given a more evocative name.)
The code for several of the core traits doesn't use hygenic macros. This isn't a problem, except for the Debug trait, which is the only one that uses a variable, named "builder". Variables can't share names with unit structs, so attempting to [derive(Debug)] on any type while a unit struct with the name "builder" was in scope would result in an error. This commit just changes the name of the variable to "__debug_trait_builder", because I couldn't figure out how to get a list of all unit structs in-scope from within the derive expansion function. If someone wants to have a unit struct with the exact name "__debug_trait_builder", they'll just have to do it without a [derive(Debug)].
Pulls in a redesigned `std::simd` module as well as a replacement for the `is_target_feature_detected!` macro
rephrase UnsafeCell doc As shown by discussions on users.rust-lang.org [[1]], [[2]], UnsafeCell doc is not totally clear. I tried to made the doc univocal regarding what is allowed and what is not. The edits are based on my understanding following [[1]].

Update Feature Request instructions As noted in rust-lang#48393 the contribution instructions for submitting a Feature Request are a little hasty, suggesting that the user immediately create an issue in the RFC repository. For users that want to submit a feature request, let's instead point them directly to the README file for the RFC repository, which contains detailed instructions on how to submit a Feature Request.
Update L4Re target specification Due to the dynamically generated linker arguments of the L4Re build system, it is not a good idea to hard-code them in Rust. This PR undoes this step. It also adds an empty implementation to retrieve the number of CPUs.
…labnik Propagating upstream code of conduct changes [This repository's code of conduct](https://github.com/rust-lang/rust/blob/master/CODE_OF_CONDUCT.md) is out of sync with the [rust-www code of conduct](https://github.com/rust-lang/rust-www/blob/master/en-US/conduct.md) due changes from rust-lang/prev.rust-lang.org#1062. This PR propagates those changes and brings the files back into sync. r? @steveklabnik

…etrochenkov Fix hygene issue when deriving Debug The code for several of the core traits doesn't use hygenic macros. This isn't a problem, except for the Debug trait, which is the only one that uses a variable, named "builder". Variables can't share names with unit structs, so attempting to [derive(Debug)] on any type while a unit struct with the name "builder" was in scope would result in an error.

If someone wants to have a unit struct with the exact name "__debug_trait_builder", they'll just have to do it without a [derive(Debug)]. I also checked the implementations of the other built-in derives to ensure they didn't declare any variables.

…g, r=QuietMisdreavus Remember state of top-level collapse toggle widget This change allows the big top-right expand/collapse toggle to remember its setting across navigation or page reloads. Prior to this change, there was this annoyance: - browse to some docs - Click the minus button to collapse them - browse to other docs (or reload the page) - Everything is expanded again The solution is based on storing a simple boolean flag in localStorage. I think it's a good improvement, but it does introduce the following potentially surprising behavior: - browse to some docs - click the minus button to collapse them - click to expand a particular item (not the main top-right big one) - reload the page, everything is collapsed Paired with @DebugSteven on this.
