Add entry-like methods to HashSet
* `HashSet::get_or_insert`
* `HashSet::get_or_insert_with`
These provide a simplification of the `Entry` API for `HashSet`, with
names chosen to match the similar methods on `Option`.
Fix .natvis visualizers.
### Updated to handle these changes:
- `core::ptr::*` lost their `__0` elements and are just plain pointers
- `core::ptr::*` probably shouldn't dereference in `DisplayString` s
- `VecDeque` probably *should* dereference it's buf pointer to display individual items.
- `VecDeque` and `Vec` use `core::ptr::*` s
- `VecDeque` and `LinkedList` moved modules again.
### Retested - still working fine, left alone:
- `String`, `&str`, `Option`
### Side Chatter
- Props to Alex for pointing out this was broken in the `#ides-and-editors` Discord channel
- It'd be nice if there was a sane way to automate unit testing these visualizers.
(I assume COM automation of Visual Studio would be a no go on the build servers, and probably really incredibly painful to write too! Suggestions welcome...)
Switch to SPDX 2.1 license expression
[According to the Cargo Reference:](https://doc.rust-lang.org/cargo/reference/manifest.html)
> This is an SPDX 2.1 license expression for this package. Currently crates.io will validate the license provided against a whitelist of known license and exception identifiers from the SPDX license list 2.4. Parentheses are not currently supported.
>
> Multiple licenses can be separated with a \`/\`, although that usage is deprecated. Instead, use a license expression with AND and OR operators to get more explicit semantics.
The notation with slashes is deprecated in favor of explicit AND or OR.
As I understand it, Rust's license is MIT *OR* Apache-2.0 matching the meaning of *OR* defined by [SPDX Specification 2.1](https://spdx.org/spdx-specification-21-web-version):
> If presented with a choice between two or more licenses, use the disjunctive binary "OR" operator to construct a new license expression, where both the left and right operands are valid license expression values.
* `HashSet::get_or_insert`
* `HashSet::get_or_insert_with`
These provide a simplification of the `Entry` API for `HashSet`, with
names chosen to match the similar methods on `Option`.
This commit gives each stable keyword a short entry in the "Keywords"
section in the docs for `std`. The newly added entries are a single
summary line and a note that the documentation is not yet complete. I
changed some of the existing summary lines for consistency's sake. Each
line is either a verb phrase ("name the type of a trait object" for
`dyn`), or an object ("A value of type `bool` representing logical true"
for `true`). I tried to avoid using the keyword itself or the word
"keyword" in the summary.
Later PRs can flesh out each keyword with an example of each
context in which a keyword can appear and a link to the rust book.
Keywords which are not close to stable rust such as `box` (which is
getting unstabilized) or `try` are ignored in this PR.
Update release notes for 1.35.0
(Applied remaining nit, rebased onto master, and added CVE link to the 1.34.2 release notes, as discussed in the release team meeting)
r? @pietroalbini
Document the `html_root_url` doc attribute value.
I'm not sure if this was intentionally not documented, but I think it would be good to include. This was added in #9691. `--extern-html-root-url` is unstable, but I don't think it hurts to mention it.

Update rustc book CLI docs.
This adds a little detail (and missing flags) to the rustc book. There is still a lot of information missing, but this seemed like a good step to expanding it.
Include expression to wait for to the span of Await
Currently the span of `await!` only includes itself:
```rust
await!(3);
// ^^^^^
```
This PR changes it so that the span holds the whole `await!` expression:
```rust
await!(3);
// ^^^^^^^^^
string: implement From<&String> for String
Allow Strings to be created from borrowed Strings. This is mostly
to make things like passing `&String` to an `impl Into<String>`
parameter frictionless.
Fixes#59827.
Move token tree related lexer state to a separate struct
Just a types-based refactoring.
We only used a bunch of fields when tokenizing into a token tree, so let's move them out of the base lexer
