fix: Fix inlay hint resolution being broken
So, things broke because we now store a hash (u64) in the resolution payload, but javascript and hence JSON only support integers of up to 53 bits (anything beyond gets truncated in various ways) which caused almost all hashes to always differ when resolving them. This masks the hash to 53 bits to work around that.

fix: VFS should not confuse paths with source roots that have the same prefix
Previously, the VFS would assign paths to the source root that had the longest string prefix match. This would break when we had source roots in subdirectories:
```
/foo
/foo/bar
```
Given a file `/foo/bar_baz.rs`, we would attribute it to the `/foo/bar` source root, which is wrong.
As a result, we would attribute paths to the wrong crate when a crate was in a subdirectory of another one. This is more common in larger monorepos, but could occur in any Rust project.
Fix this in the VFS, and add a test.
Run Windows tests on PRs too
Previously PRs would only do a build on Windows, which confusingly meant that PRs got a green tick for Windows despite not testing them.
See discussion in #17019.
internal: make function builder create ast directly
I am working on #17050.
In the process, I noticed a place in the code that could be refactored.
Currently, the `function builder` creates the `ast` through the `function template` , but those two processes can be combined into one function.
I thought I should work on this first and created a PR.
Add add/sub methods that only panic with debug assertions to rustc
This mitigates the perf impact of enabling overflow checks on rustc. The change to use overflow checks will be done in a later PR.
For rust-lang/compiler-team#724, based on data gathered in #119440.
Re-enable `has_thread_local` for i686-msvc
A few years back, `has_thread_local` was disabled as a workaround for a compiler issue. While the exact cause was never tracked down, it was suspected to be caused by the compiler inlining a thread local access across a dylib boundary. This should be fixed now so let's try again.
Do not accept the following
```rust
macro_rules! lexes {($($_:tt)*) => {}}
lexes!(🐛"foo");
```
Before, invalid emoji identifiers were gated during parsing instead of lexing in all cases, but this didn't account for macro expansion of literal prefixes.
Fix#123696.
Propagate temporary lifetime extension into if and match.
This PR makes this work:
```rust
let a = if true {
..;
&temp() // used to error, but now gets lifetime extended
} else {
..;
&temp() // used to error, but now gets lifetime extended
};
```
and
```rust
let a = match () {
_ => {
..;
&temp() // used to error, but now gets lifetime extended
}
};
```
to make it consistent with:
```rust
let a = {
..;
&temp() // lifetime is extended
};
```
This is one small part of [the temporary lifetimes work](https://github.com/rust-lang/lang-team/issues/253).
This part is backwards compatible (so doesn't need be edition-gated), because all code affected by this change previously resulted in a hard error.
Specialize many implementations of `Read::read_buf_exact`
This makes all implementations of `Read` that have a specialized `read_exact` implementation also have one for `read_buf_exact`.
Show mode_t as octal in std::fs Debug impls
Example:
```rust
fn main() {
println!("{:?}", std::fs::metadata("Cargo.toml").unwrap().permissions());
}
```
- Before: `Permissions(FilePermissions { mode: 33204 })`
- ~~After: `Permissions(FilePermissions { mode: 0o100664 })`~~
- After: `Permissions(FilePermissions { mode: 0o100664 (-rw-rw-r--) })`
~~I thought about using the format from `ls -l` (`-rw-rw-r--`, `drwxrwxr-x`) but I am not sure how transferable the meaning of the higher bits between different unix systems, and anyway starting the value with a leading negative-sign seems objectionable.~~
Document enabling the flatpak rust SDK extension
Just having `org.freedesktop.Sdk.Extension.rust-stable` and `org.freedesktop.Sdk.Extension.llvm15` installed is not enough.
`/usr/lib/sdk/rust-stable/bin` at least needs to be added to the `PATH`.
In the case of VSCodium [ide-flatpak-wrapper](https://github.com/noonsleeper/ide-flatpak-wrapper) in included to do this.
Replace some `CrateStore` trait methods with hooks.
Just like with the `CrateStore` trait, this avoids the cyclic definition issues with `CStore` being
defined after TyCtxt, but needing to be used in TyCtxt.
Previously PRs would only do a build on Windows, which confusingly
meant that PRs got a green tick for Windows despite not testing them.

Try using a `dyn Debug` trait object instead of a closure
These closures were introduced in https://github.com/rust-lang/rust/pull/93098
let's see if we can't use fmt::Arguments instead
