Update deps of bootstrap for Cygwin
This PR just runs
```
cargo update fd-lock xattr libc errno
```
It reduces dependency on `rustix 0.38.40` and updates `libc` & `errno`. Now it compiles successfully on Cygwin:)
implement `PanicTracker` to track `t` panics
Trying to understand panics triggered by `t` macro is very exhausting (especially on CI failures) because it doesn't provide any information about where the macro was originally invoked. This change adds that missing information when an inner call inside the `t` macro panics.
Resolves#137557
bypass linker configuration and cross target check on `x check`
I was going to handle this using the untracked env approach, but I realized it somehow doesn't regress https://github.com/rust-lang/rust/issues/130108 anymore...
Anyway, if it works, it works. 😄 No need to dig deeper but my guess is we moved some cache-invalidating env from these functions to others.
Fixes https://github.com/rust-lang/rust/issues/133840

Add `rust.debug-assertions-tools` option
Before this PR, the two only options to configure the presence of debug assertions were the `rust.debug-assertions` and `rust.debug-assertions-std` options. The former applied to everything, and the latter allowed to override the setting just for the standard library. This combination of settings doesn't allow to enable debug assertions for the std and the compiler but not tools.
Some tools (like Cargo) are not really meant to be executed with debug assertions enabled, and in Ferrocene we hit some debug assertions in it that are exclusively meant for its test suite. We'd thus like to enable debug assertions everywhere but in tools.
This PR adds a `rust.debug-assertions-tools` setting that does exactly this.
compiletest: Remove the libtest-based executor and its dependency
Now that #140288 has landed and the new compiletest executor is used by default, we can now move forward with removing the libtest dependency from compiletest.
My hope is that after landing this, we can configure bootstrap to build compiletest with the pre-built stage0 library by default, instead of the in-tree stage0 library. That would give the stage0 redesign one less thing to worry about.

Remove git repository from git config
It is no longer needed after https://github.com/rust-lang/rust/pull/138591. We could even remove the `nightly_branch` field, but it still has one usage.
r? ``@jieyouxu``
I found these by grepping for `&[a-z_\.]*\.clone()`, i.e. expressions
like `&a.b.clone()`, which are sometimes unnecessary clones, and also
looking at clones nearby to cases like that.
Clippy subtree update
r? `@Manishearth`
Cargo.lock update due to the Clippy version bump and because Clippy moved from rinja (unmaintained) to askama.
Last sync was skipped due to the askama issue and me not getting to fixing this in time.
skip llvm-config in autodiff check builds, when its unavailable
As you suggested, this indeed fixes `./x.py check` builds when autodiff is enabled.

Setup editor file associations for non-rs extensions
.gitattributes lists `*.fixed`, `*.pp`, and `*.mir` as file extensions which should be treated as Rust source code. Do the same for VS Code and Zed. This only does syntax highlighting, which is appropriate, as MIR isn't really Rust code.
At the same time, consistently order `rust-analyzer.linkedProjects` between editors. For some reason, Eglot didn't include `library/Cargo.toml`.
I have tested this with VS Code and Zed. I have not implemented it for Emacs/Eglot or Helix.
support config extensions
_Copied from the `rustc-dev-guide` addition:_
>When working on different tasks, you might need to switch between different bootstrap >configurations.
>Sometimes you may want to keep an old configuration for future use. But saving raw config >values in
>random files and manually copying and pasting them can quickly become messy, especially if >you have a
>long history of different configurations.
>
>To simplify managing multiple configurations, you can create config extensions.
>
>For example, you can create a simple config file named `cross.toml`:
>
>```toml
>[build]
>build = "x86_64-unknown-linux-gnu"
>host = ["i686-unknown-linux-gnu"]
>target = ["i686-unknown-linux-gnu"]
>
>
>[llvm]
>download-ci-llvm = false
>
>[target.x86_64-unknown-linux-gnu]
>llvm-config = "/path/to/llvm-19/bin/llvm-config"
>```
>
>Then, include this in your `bootstrap.toml`:
>
>```toml
>include = ["cross.toml"]
>```
>
>You can also include extensions within extensions recursively.
>
>**Note:** In the `include` field, the overriding logic follows a right-to-left order. For example,
in `include = ["a.toml", "b.toml"]`, extension `b.toml` overrides `a.toml`. Also, parent extensions
always overrides the inner ones.
