These functions were added to all preludes in Rust 1.80.
Since the error kind (`io::ErrorKind::other`) is in the root context,
the error message must be found in the root context as well to compute
the correct span to remove.

Make CrateItem::body() function return an option
When we initially created `CrateItem`, it would only represent items that contain a body.
That is no longer the case, for now, make this explicit by expanding the APIs to retrieve the item body.
This is related to https://github.com/rust-lang/project-stable-mir/issues/34

Pretty-print `#[deprecated]` attribute in HIR.
Pretty-print `#[deprecated]` attribute in a form closer to how it might appear in Rust source code, rather than using a `Debug`-like representation.
Consider the following Rust code:
```rust
#[deprecated]
pub struct PlainDeprecated;
#[deprecated = "here's why this is deprecated"]
pub struct DirectNote;
#[deprecated(since = "1.2.3", note = "here's why this is deprecated")]
pub struct SinceAndNote;
```
Here's the previous output:
```
#[attr="Deprecation{deprecation: Deprecation{since: Unspecifiednote:
suggestion: }span: }")]
struct PlainDeprecated;
#[attr="Deprecation{deprecation: Deprecation{since: Unspecifiednote:
here's why this is deprecatedsuggestion: }span: }")]
struct DirectNote;
#[attr="Deprecation{deprecation: Deprecation{since: NonStandard(1.2.3)note:
here's why this is deprecatedsuggestion: }span: }")]
struct SinceAndNote;
```
Here's the new output:
```rust
#[deprecated]
struct PlainDeprecated;
#[deprecated = "here's why this is deprecated"]
struct DirectNote;
#[deprecated(since = "1.2.3", note = "here's why this is deprecated"]
struct SinceAndNote;
```
Also includes a test for `#[diagnostic::(..)]` attributes, though their behavior is not changed here. I already wrote the test, so I figured it probably won't hurt to have it.
Related to discussion in #137645.

rustdoc search: increase strictness of typechecking
r? `@notriddle`
The signature of `makePrimitiveElement` is now more accurate.
I believe the intent of the code is that `name` cannot be null if `bindingName.name` is null, and I believe typescript is expressive enough to encode this, but I'm not quite sure how, or if this would be desirable.
I'm also introducing mapped types into `rustdoc.d.ts`, but I think it's worth it in order to avoid keeping two interfaces in sync.
I may add more commits onto this to remove more ``@ts-expect-error`` instances.
Remove unused `PpMode::needs_hir`
This method was added in #99360 to avoid an overzealous `span_delayed_bug` ICE in specific circumstances, but the only caller was subsequently removed in #136603, which presumably avoids the problem in a more principled way.
Update MSVC INSTALL.md instructions to recommend VS 2022 + recent Windows 10/11 SDK
This is generally iffy because we don't consistently [document the exact minimum versions of build tools required to build a given Rust toolchain](https://github.com/rust-lang/rust/issues/129307).
cc #129307, *maybe* rustup docs are outdated?
Anyway, I updated this because I was on a slightly older VS toolchain and I couldn't `./x build library` on MSVC (even though maybe a month ago I could) due to CI `rustc_llvm` using stuff from newer Windows 11 SDK maybe. I updated the VS toolchain + Windows 11 SDK, and then I could build.
I'm not 100% sure the requirements here are accurate. It might be too high?

Simplify `<Postorder as Iterator>::size_hint`
The current version is sometimes malformed (cc #137919); let's see if we can get away with a loose but trivially-correct one.
Allow struct field default values to reference struct's generics
Right now, the default field value feature (https://github.com/rust-lang/rust/issues/132162) lowers anon consts whose types may reference ADT params that the const doesn't inherit.
This PR fixes this, so that these defaults can reference ADTs' generics, and sets the `generics_of` parenting up correctly.
There doesn't seem to be a good reason not to support this, since the anon const has a well-defined type from the field, and the anon const doesn't interact with the type system like generic parameter defaults do.
r? `````@boxyuwu````` or reassign
I could also make this into an error if this seems problematic (https://github.com/rust-lang/rust/compare/master...compiler-errors:rust:default-field-value-implicit-param?expand=1)...... but I'd rather make this work and register an open question on the tracking issue about validating that this is well-vetted.
Fixes#137896
