Trigger VSCode to rename after extract variable assist is applied
When the user applies the "Extract Variable" assist, the cursor is
positioned at the newly inserted variable. This commit adds a command
to the assist that triggers the rename action in VSCode. This way, the
user can quickly rename the variable after applying the assist.
Fixes part of: #17579

I haven't yet looked at the module or function extraction assists yet.

Implement symbol interning infra
Will fix https://github.com/rust-lang/rust-analyzer/issues/15590
My unsafe-fu is not the best but it does satisfy miri.
There is still some follow up work to do, notably a lot of places using strings instead of symbols/names, most notably the token tree.

- move `edit.rename()` to the end of the function
- use a match statement to set `res.command`

Add `f16` and `f128` as simd types in LLVM
`@sayantn` is working on adding SIMD for `f16` and hitting the `FloatingPointVector` error. This should fix it and unblock adding support for `simd_fma` and `simd_fabs` in stdarch.

Avoid follow-up errors and ICEs after missing lifetime errors on data structures
Tuple struct constructors are functions, so when we call them typeck will use the signature tuple struct constructor function to provide type hints. Since typeck mostly ignores and erases lifetimes, we end up never seeing the error lifetime in writeback, thus not tainting the typeck result.
Now, we eagerly taint typeck results by tainting from `resolve_vars_if_possible`, which is called all over the place.
I did not carry over all the `crashes` test suite tests, as they are really all the same cause (missing or unknown lifetime names in tuple struct definitions or generic arg lists).

Require a colon in `//@ normalize-*:` test headers
The previous parser for `//@ normalize-*` headers (before #126370) was so lax that it did not require `:` after the header name. As a result, the test suite contained a mix of with-colon and without-colon normalize headers, both numbering in the hundreds.
This PR updates the without-colon headers to add a colon (matching the style used by other headers), and then updates the parser to make the colon mandatory.
(Because the normalization parser only runs *after* the header system identifies a normalize header, this will detect and issue an error for relevant headers that lack the colon.)
Addresses one of the points of #126372.

feat: do not add new enum if it already exists
## Summary
This PR introduces a check for the existence of another enum within the current scope, and if it exist, we skip `add_enum_def`.
## Why?
Currently, when using the `bool_to_enum` assist more than once, it is possible to add multiple enum definitions. For example, the following snippet,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = true;
println!("Hello, world!");
}
```
will be transformed into,
```rs
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
#[derive(PartialEq, Eq)]
enum Bool {
True,
False,
}
fn main() {
let a = Bool::True;
let b = Bool::True;
println!("Hello, world!");
}
```
This can be annoying for users to clean up.

Implement simple, unstable lint to suggest turning closure-of-async-block into async-closure
We want to eventually suggest people to turn `|| async {}` to `async || {}`. This begins doing that. It's a pretty rudimentary lint, but I wanted to get something down so I wouldn't lose the code.
Tracking:
* #62290

Avoid "no field" error and ICE on recovered ADT variant
Fixes https://github.com/rust-lang/rust/issues/126744
Fixes https://github.com/rust-lang/rust/issues/126344, a more general fix compared with https://github.com/rust-lang/rust/pull/127426
r? `@oli-obk`
From `@compiler-errors` 's comment https://github.com/rust-lang/rust/pull/127502#discussion_r1669538204
Seems most of the ADTs don't have taint, so maybe it's not proper to change `TyCtxt::type_of` query.

Migrate `issue-83112-incr-test-moved-file`, `type-mismatch-same-crate-name` and `issue-109934-lto-debuginfo` `run-make` tests to rmake or ui
Part of #121876 and the associated [Google Summer of Code project](https://blog.rust-lang.org/2024/05/01/gsoc-2024-selected-projects.html).
I have noticed that the new UI test `debuginfo-lto-alloc` is outputting artifacts that aren't getting cleaned up because of its `-C incremental`. That might be the justification needed to keep it as a run-make test?
Try it on:
// try-job: test-various // previously passed
try-job: armhf-gnu
try-job: aarch64-apple
try-job: x86_64-msvc

Fix local download of Docker caches from CI
https://github.com/rust-lang/rust/pull/127312 broke local downloads of Docker caches from CI, when you wanted to build a Docker image locally. This PR fixes that.

instantiate higher ranked goals in candidate selection again
This reverts #119820 as that PR has a significant impact and breaks code which *feels like it should work*. The impact ended up being larger than we expected during the FCP and we've ended up with some ideas for how we can work around this issue in the next solver. This has been discussed in the previous high bandwidth t-types meeting: https://rust-lang.zulipchat.com/#narrow/stream/326132-t-types.2Fmeetings/topic/2024-07-09.20high.20bandwidth.20meeting.
We'll therefore keep this inconsistency between the two solvers for now and will have to deal with it before stabilizating the use of the new solver outside of coherence: https://github.com/rust-lang/trait-system-refactor-initiative/issues/120.
fixes #125194 after a beta-backport.
The pattern which is more widely used than expected and feels like it should work, especially without deep knowledge of the type system is
```rust
trait Trait<'a> {}
impl<'a, T> Trait<'a> for T {}
fn trait_bound<T: for<'a> Trait<'a>>() {}
// A function with a where-bound which is more restrictive than the impl.
fn function1<T: Trait<'static>>() {
// stable: ok
// with #119820: error as we prefer the where-bound over the impl
// with this PR: back to ok
trait_bound::<T>();
}
```

Fix running bootstrap tests with a local Rust toolchain as the stage0
When configuring a local Rust toolchain as the stage0 (with `build.rustc` and `build.cargo` in `config.toml`) we noticed there were test failures (both on the Python and the Rust side) due to bootstrap not being able to find rustc and Cargo.
This was due to those two `config.toml` settings not being propagated in the tests. This PR fixes the issue by ensuring rustc and cargo are always configured in tests, using the parent bootstrap's `initial_rustc` and `initial_cargo`.

Exposing STARTUPINFOW.wShowWindow in CommandExt trait
Hi:
I needed a way to control how a new process's window is displayed in Windows (normal, minimized, maximized, etc).
I noticed that there is no direct way to do that (I even searched for crates doing this, but didn't find any).
Inspecting the standard library source code, I figured that it would be a good addition to CommandExt trait that allows some Windows specific customization to a Command.
This is my first time contributing to Rust, so please bear with me if I'm not following the rules :)

Add `f16` and `f128` support
Adds `f16` and `f128` support, using the `rustc_apfloat` library (also used by `rustc`) for parsing/arithmetic/displaying since the types aren't stable yet so can't be used by rust-analyzer itself.

feat: add inlay hints for generic parameters
fixes #11091
By default, only hints for const generic parameters are shown, and this can be configured through `rust-analyzer.inlayHints.genericParameterHints.enable`.
Probably needs more testing.
