By nobuild, I mean that the type annotations are all in comments,
not in the "native" typescript syntax. This is a bit uglier,
but it lets you rapid-prototype without tsc, works with all
the native browser debugging tools, and keeps Node out of Rust's
bootstrap chain.
This pull request mostly just adds ts-ignore annotations
and type declarations. To actually take good advantage of
typescript, we'll want to "burn down" this pile of unsafe code
until we eventually have a version with almost none of these.
This PR also adds tsc to the mingw-check Dockerfile, so that
it can't fall out of date like the Closure annotations did.

Remove extra whitespace from rustdoc breadcrumbs for copypasting
The docs header used to display [item names with their full path](https://doc.rust-lang.org/1.82.0/std/os/unix/ffi/trait.OsStrExt.html), but a [recent design change](https://doc.rust-lang.org/1.83.0/std/os/unix/ffi/trait.OsStrExt.html) has split the path and added extra styling to it.
The problem is the new styling affects how this text is copied to clipboard. I used to copy and paste the paths into `use` statements in the code, but the new styling has extra formatting and whitespace that makes copied text unusable in Rust source code.
Instead of:
> std::os::unix::ffi::OsStrExt
I now get:
> std
> ::
> os
> ::
> unix
> ::
> ffi
> Trait OsStrExt
This change removes extra whitespace from the markup, and removes `display: flex`. Paths (now in small text) are unlikely to be that long to wrap, and even then regular text wrapping should be sufficient.

Forbid usage of `hir` `Infer` const/ty variants in ambiguous contexts
The feature `generic_arg_infer` allows providing `_` as an argument to const generics in order to infer them. This introduces a syntactic ambiguity as to whether generic arguments are type or const arguments. In order to get around this we introduced a fourth `GenericArg` variant, `Infer` used to represent `_` as an argument to generic parameters when we don't know if its a type or a const argument.
This made hir visitors that care about `TyKind::Infer` or `ConstArgKind::Infer` very error prone as checking for `TyKind::Infer`s in `visit_ty` would find *some* type infer arguments but not *all* of them as they would sometimes be lowered to `GenericArg::Infer` instead.
Additionally the `visit_infer` method would previously only visit `GenericArg::Infer` not *all* infers (e.g. `TyKind::Infer`), this made it very easy to override `visit_infer` and expect it to visit all infers when in reality it would only visit *some* infers.
---
This PR aims to fix those issues by making the `TyKind` and `ConstArgKind` types generic over whether the infer types/consts are represented by `Ty/ConstArgKind::Infer` or out of line (e.g. by a `GenericArg::Infer` or accessible by overiding `visit_infer`). We then make HIR Visitors convert all const args and types to the versions where infer vars are stored out of line and call `visit_infer` in cases where a `Ty`/`Const` would previously have had a `Ty/ConstArgKind::Infer` variant:
API Summary
```rust
enum AmbigArg {}
enum Ty/ConstArgKind<Unambig = ()> {
...
Infer(Unambig),
}
impl Ty/ConstArg {
fn try_as_ambig_ty/ct(self) -> Option<Ty/ConstArg<AmbigArg>>;
}
impl Ty/ConstArg<AmbigArg> {
fn as_unambig_ty/ct(self) -> Ty/ConstArg;
}
enum InferKind {
Ty(Ty),
Const(ConstArg),
Ambig(InferArg),
}
trait Visitor {
...
fn visit_ty/const_arg(&mut self, Ty/ConstArg<AmbigArg>) -> Self::Result;
fn visit_infer(&mut self, id: HirId, sp: Span, kind: InferKind) -> Self::Result;
}
// blanket impl'd, not meant to be overriden
trait VisitorExt {
fn visit_ty/const_arg_unambig(&mut self, Ty/ConstArg) -> Self::Result;
}
fn walk_unambig_ty/const_arg(&mut V, Ty/ConstArg) -> Self::Result;
fn walk_ty/const_arg(&mut V, Ty/ConstArg<AmbigArg>) -> Self::Result;
```
The end result is that `visit_infer` visits *all* infer args and is also the *only* way to visit an infer arg, `visit_ty` and `visit_const_arg` can now no longer encounter a `Ty/ConstArgKind::Infer`. Representing this in the type system means that it is now very difficult to mess things up, either accessing `TyKind::Infer` "just works" and you won't miss *some* type infers- or it doesn't work and you have to look at `visit_infer` or some `GenericArg::Infer` which forces you to think about the full complexity involved.
Unfortunately there is no lint right now about explicitly matching on uninhabited variants, I can't find the context for why this is the case :woman_shrugging:
I'm not convinced the framing of un/ambig ty/consts is necessarily the right one but I'm not sure what would be better. I somewhat like calling them full/partial types based on the fact that `Ty<Partial>`/`Ty<Full>` directly specifies how many of the type kinds are actually represented compared to `Ty<Ambig>` which which leaves that to the reader to figure out based on the logical consequences of it the type being in an ambiguous position.

rustdoc-json: Rename `Path::name` to `path`, and give it the path again.
Closes: #135600.
Reverts #134880 (Effectively, but not actually, as the `FORMAT_VERSION` needs to be bumped, changed docs/tests). CC `@AS1100K.`
Also CC `@obi1kenobi` `@LukeMathWalker`
Still needs before being merge-ready:
- [x] Tests for cross-crate paths
- [x] (Maybe) Document what the field does.
- [x] Decide if the field rename is good (https://github.com/rust-lang/rust/pull/135799#issuecomment-2605937831)
- [ ] Squash commits.

Get rid of RunCompiler
The various `set_*` methods that have been removed can be replaced by setting the respective fields in the `Callbacks::config` implementation. `set_using_internal_features` was often forgotten and it's equivalent is now done automatically.

Refactor `fmt::Display` impls in rustdoc
This PR does a couple of things, with the intention of cleaning up and streamlining some of the `fmt::Display` impls in rustdoc:
1. Use the unstable [`fmt::from_fn`](https://github.com/rust-lang/rust/issues/117729) instead of open-coding it.
2. ~~Replace bespoke implementations of `Itertools::format` with the method itself.~~
4. Some more minor cleanups - DRY, remove unnecessary calls to `Symbol::as_str()`, replace some `format!()` calls with lazier options
The changes are mostly cosmetic but some of them might have a slight positive effect on performance.

rustdoc: Remove `AttributesExt` trait magic that added needless complexity
The new code is more explicit and avoids trait magic that added needless

r=davidtwco
deprecate `std::intrinsics::transmute` etc, use `std::mem::*` instead
The `rustc_allowed_through_unstable_modules` attribute lets users call `std::mem::transmute` as `std::intrinsics::transmute`. The former is a reexport of the latter, and for a long time we didn't properly check stability for reexports, so making this a hard error now would be a breaking change for little gain. But at the same time, `std::intrinsics::transmute` is not the intended path for this function, so I think it is a good idea to show a deprecation warning when that path is used. This PR implements that, for all the functions in `std::intrinsics` that carry the attribute.
I assume this will need ``@rust-lang/libs-api`` FCP.

Treat safe target_feature functions as unsafe by default [less invasive variant]
This unblocks
* #134090
As I stated in https://github.com/rust-lang/rust/pull/134090#issuecomment-2541332415 I think the previous impl was too easy to get wrong, as by default it treated safe target feature functions as safe and had to add additional checks for when they weren't. Now the logic is inverted. By default they are unsafe and you have to explicitly handle safe target feature functions.
This is the less (imo) invasive variant of #134317, as it doesn't require changing the Safety enum, so it only affects FnDefs and nothing else, as it should.

Made `Path::name` only have item name rather than full name
Closes #134853
This PR makes `Path::name` to only have item name rather than full name, i.e. with the following code
```rust
pub mod foo {
pub struct Bar;
}
pub fn get_bar() -> foo::Bar {
foo::Bar
}
```
and running `./rustdoc ./demo.rs -wjson -Zunstable-options` gives:
```json
{
"41": {
"id": 41,
"name": "get_bar",
"inner": {
"function": {
"sig": {
"inputs": [],
"output": {
"resolved_path": {
"name": "Bar",
"id": 0,
"args": { "angle_bracketed": { "args": [], "constraints": [] }
}
}
}

Enable "jump to def" feature on patterns
Part of https://github.com/rust-lang/rust/issues/89095.
Pattern (as in "patterns in pattern matching") were not handled by the feature, it's now added.
It all started when I realized that prelude values like `Some` or `Err` were not getting a link generated either (added support for it in the first commit).

A clone-like function in a function that takes as an argument the type
that it returns.
However, functions that return a type variable are not counted as
clone-line. Because we're not unifying the whole function at once,
a function like `U -> T` would otherwise be counted as "clone-like"
because the generics will just unify with anything when done seperatly.
