These `into_iter()` calls will change from iterating references to
values if we ever get `IntoIterator` for arrays, which may break the
code using that iterator. Calling `iter()` is future proof.

Prevent Error::type_id overrides
type_id now takes an argument that can't be named outside of the
std::error module, which prevents any implementations from overriding
it. It's a pretty grody solution, and there's no way we can stabilize
the method with this API, but it avoids the soudness issue!
Closes#60784

Update the compiler_builtins crate
This updates to 0.1.13 for `compiler_builtins`, published to fix a few
issues. The feature changes here are updated because `compiler_builtins`
no longer enables the `c` feature by default but we want to do so
through our build still.

Checking generic args after late bound region err.
Fixes#60622.
This PR fixes an ICE that occurs when a late bound region error is
emitted and that resulted in the rest of the generic arguments of a
function not being checked.
For example, you could specify a generic type parameter `T` in a function
call `foo<'_, T>()` to a function that doesn't have a generic type
parameter.
Since an error wasn't emitted from the function, compilation
continued to parts of typeck that didn't expect a generic type argument
in a call for a function that didn't have any generic type arguments.

Add stubs to keyword docs
Resolves#60779.
This commit gives each stable keyword a short entry in the "Keywords" section in the docs for `std`. The newly added entries are only a single line each and contain the main purpose of the keyword. I changed some of the existing summary lines for consistency's sake. Each line is either an imperative ("name the type of a trait object" for `dyn`), or an object ("An abstract data type" for `enum`). I tried to avoid using the keyword itself or the word "keyword" in the summary.
Later commits can flesh out each keyword with an example for each context in which it can appear as well as a link to the appropriate part of the rust book.
**edit:**
Here's the list of keywords and summaries (sans formatting) to ease reviewing. I'll try to keep this up to date as I make changes:
keyword | summary
-- | --
Self | The implementing type within a `trait` or `impl` block, or the current type within a type definition.
as | Cast between types, or rename an import.
async | ExperimentalReturn a Future instead of blocking the current thread.
await | ExperimentalSuspend execution until the result of a Future is ready.
break | Exit early from a loop.
const | Compile-time constants and deterministic functions.
continue | Skip to the next iteration of a loop.
crate | A Rust binary or library.
dyn | Name the type of a trait object.
else | What to do when an if condition does not hold.
enum | A type that can be any one of several variants.
extern | Link to or import external code.
false | A value of type bool representing logical false.
fn | A function or function pointer.
for | Iteration with in, trait implementation with impl, or higher-ranked trait bounds (for<'a>).
if | Evaluate a block if a condition holds.
impl | Implement some functionality for a type.
in | Iterate over a series of values with for.
let | Bind a value to a variable.
loop | Loop indefinitely.
match | Control flow based on pattern matching.
mod | Organize code into modules.
move | Capture a closure's environment by value.
mut | A mutable binding, reference, or pointer.
pub | Make an item visible to others.
ref | Bind by reference during pattern matching.
return | Return a value from a function.
self | The receiver of a method, or the current module.
static | A place that is valid for the duration of a program.
struct | A type that is composed of other types.
super | The parent of the current module.
trait | A common interface for a class of types.
true | A value of type bool representing logical true.
type | Define an alias for an existing type.
union | The Rust equivalent of a C-style union.
unsafe | Code or interfaces whose memory safety cannot be verified by the type system.
use | Import or rename items from other crates or modules.
where | Add constraints that must be upheld to use an item.
while | Loop while a condition is upheld.
type_id now takes an argument that can't be named outside of the
std::error module, which prevents any implementations from overriding
it. It's a pretty grody solution, and there's no way we can stabilize
the method with this API, but it avoids the soudness issue!
Closes#60784
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.
