`try_fold_unevaluated` for infallible folders #97447 added folding of unevaluated constants, but did not include an override of the default (fallible) operation in the blanket impl of `FallibleTypeFolder` for infallible folders. Here we provide that missing override. r? ```@nnethercote```

Improve loading of crates.js and sidebar-items.js Now that the "All Crates" dropdown is only rendered on the search results page, there is no need to load crates.js on most pages. Load it only on crate pages. Also, add the `defer` attribute so it does not block HTML parsing. For sidebar-items.js, move the script tag to `<head>`. Since it already has the defer attribute it won't block loading. The defer attribute does preserve ordering between scripts, so instead of the callback on load, it can set a global variable on load, which is slightly simpler. Also, since it is required to finish rendering the page, beginning its load earlier is better. Remove generation and handling of sidebar-vars. Everything there can be computed with information available in JS via other means. Remove the extra_scripts fields of the `Page` template. They were only used by source-script.js and source-files.js, which are now linked by the template based on whether it is rendering a source page. Remove the "other" wrapper in the sidebar. It was unnecessary. r? ```@GuillaumeGomez``` Demo: https://rustdoc.crud.net/jsha/defer-crates/std/index.html

Fix erroneous span for borrowck error I am not confident that this is the correct fix, but it does the job. Open to suggestions for a real fix instead. Fixes #97997 The issue is that we pass a [dummy location](https://doc.rust-lang.org/nightly/nightly-rustc/src/rustc_middle/mir/visit.rs.html#302) when type-checking the ["required consts"](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_middle/mir/struct.Body.html#structfield.required_consts) that are needed by the MIR body during borrowck. This means that when we fail to evaluate the constant, we use the span of `bb0[0]`, instead of the actual span of the constant. There are quite a few other places that use `START_BLOCK.start_location()`, `Location::START`, etc. when calling for a random/unspecified `Location` value. This is because, unlike (for example) `Span`, we don't have a dummy/miscellaneous value to use instead. I would appreciate guidance (either in this PR, or a follow-up) on what needs to be done to clean this up in general.

Add proper tracing spans to rustc_trait_selection::traits::error_reporting While I was trying to figure out #97704 I did some of this to make the logs more legible, so I figured I'd do the whole module and open a PR with it. afaict this is an ongoing process in the compiler from the log->tracing transition? but lmk if there was a reason for the more verbose forms of logging as they are. Also, for some of the functions with only one log in them, I put the function name as a message for that log instead of `#[instrument]`-ing the whole function with a span? but maybe the latter would actually be preferable, I'm not actually sure.

Only since 1.56 is this callable in `const fn`: [changelog](https://github.com/rust-lang/rust/blob/master/RELEASES.md#version-1560-2021-10-21) Also see [Zulip discussion](https://rust-lang.zulipchat.com/#narrow/stream/122651-general/topic/transmute.20const.20fn.20stabilization).

Mention formatting macros when encountering `ArgumentV1` method in const Also open to just closing this if it's overkill. There are a lot of other distracting error messages around, so maybe it's not worth fixing just this one. Fixes #93665

Don't omit comma when suggesting wildcard arm after macro expr * Also adds `Span::eq_ctxt` to consolidate the various usages of `span.ctxt() == other.ctxt()` * Also fixes an unhygenic usage of spans which caused the suggestion to render weirdly when we had one arm match in a macro * Also always suggests a comma (i.e. even after a block) if we're rendering a wildcard arm in a single-line match (looks prettier

`Stdio::makes_pipe` Wrappers around `std::process::Command` may want to be able to override pipe creation. However, [`std::process::Stdio`](https://doc.rust-lang.org/std/process/struct.Stdio.html) is opaque so there's no way to tell if `Command` was told to create new pipes or not. This is in some ways a more generic (and cross-platform) alternative to #97149. However, unlike that feature, this comes with the price of the user needing to actually create their own pipes rather than reusing the std one. So I think it stands (or not) on its own. # Example ```rust #![feature(stdio_makes_pipe)] use std::process::Stdio; let io = Stdio::piped(); assert_eq!(io.makes_pipe(), true); ```

Windows: `CommandExt::async_pipes` Discussed in https://github.com/tokio-rs/tokio/issues/4670 was the need for third party crates to be able to force `process::Command::spawn` to create pipes as async. This implements the suggestion for a `async_pipes` method that gives third party crates that option. # Example: ```rust use std::process::{Command, Stdio}; Command::new("cmd") .async_pipes(true) .stdin(Stdio::piped()) .stdout(Stdio::piped()) .stderr(Stdio::piped()) .spawn() .unwrap(); ```
