Remove `TypeckResults` from `InferCtxt`
`InferCtxt` currently has `in_progress_typeck_results` which is only used for some diagnostics during typeck. It adds a lifetime which propagates through a lot of code. This PR moves that field into a new helper struct `TypeErrCtxt`.
fix: Make go-to-def work for `#[doc = include_str!("path")]`
See the added test, go-to-def on `#[doc = include_str!("path$0")]` should navigate to `path`.
let-else: test else block with non-never uninhabited type
let else currently does not allow uninhabited types for the `else` block that aren't `!`. One can maybe think about relaxing this in the future, but if it is done, it should be an explicit choice and not an unexpected side effect of e.g. a refactor. Thus, I'm extending a test that will fail if the behaviour changes.
Disable compressed debug sections on i586-gnu
Compressed debug is enabled by default for gas (assembly) on Linux/x86
targets, and we started building our own in #102530, but that made our
`compiler_builtins` incompatible with binutils < 2.32. Add an explicit
option to disable that in our crosstool-ng config. Fixes#102703.
rustdoc: remove unused CSS `.docblock a:not(.srclink)`
This selector was added in c7312fbae4, because the list of impl items could be nested below `docblock`.
c7312fbae4/src/librustdoc/html/render.rs (L3841-L3845)
Now that rustdoc toggles have been switched to `<details>`, there shouldn't be any need to put things inside docblock containers just to give them disclosure toggles.
rustdoc: remove unused CSS `.content .item-list`
When these rules were added in 4fd061c426 (yeah, that's the very first commit of rustdoc_ng), `.item-list` was a `<ul>`, and this would override the default style for that tag.
In c1b1d6804b, it was changed to use a `<div>` tag, so these rules are both no-ops.
The /data/tmp directory does not exist, at least not on recent versions
of Android, which currently leads to test failures on that platform. I
checked a virtual device running AOSP master and a Nexus 5 running
Android Marshmallow and on both devices the /data/tmp directory does
not exist and /data/local/tmp does, so let's switch to /data/local/tmp.

lint::unsafe_removed_from_name: fix false positive result when allowed
changelog: [`unsafe_removed_from_name`] Fix allowing on imports produces a false positive on `useless_attribute`.
Fixes: #9197

Remove `-Ztime`
Because it has a lot of overlap with `-Ztime-passes` but is generally less useful. Plus some related cleanups.

Fix overconstrained Send impls in btree internals
Fixes https://github.com/dtolnay/async-trait/issues/215.
Minimal repro:
```rust
use std::collections::btree_map::Iter;
fn require_send<T: Send>(_: T) {}
fn main() {
require_send(async {
let _iter = None::<Iter<(), &()>>;
async {}.await;
});
}
```
```console
error: higher-ranked lifetime error
--> src/main.rs:6:5
|
6 | / require_send(async {
7 | | let _iter = None::<Iter<(), &()>>;
8 | | async {}.await;
9 | | });
| |______^
|
= note: could not prove `impl Future<Output = ()>: Send`
```
Not-quite-so-minimal repro:
```rust
use std::collections::BTreeMap;
use std::future::Future;
fn spawn<T: Future + Send>(_: T) {}
async fn f() {
let map = BTreeMap::<u32, Box<dyn Send + Sync>>::new();
for _ in &map {
async {}.await;
}
}
fn main() {
spawn(f());
}
```
```console
error: higher-ranked lifetime error
--> src/main.rs:14:5
|
14 | spawn(f());
| ^^^^^^^^^^
|
= note: could not prove `impl Future<Output = ()>: Send`
```
I am not familiar with the btree internals, but it seems clear to me that the `async fn f` above should return a Send future. Using HashMap instead of BTreeMap in that code makes it already return a Send future.
The _"higher-ranked lifetime error"_ message may be a regression in Rust 1.63. Using older compilers the error message was more detailed:
```console
