Don't translate compiler-internal bug messages
These are not very useful to be translated, as
* translators would get really weird and bad english versions to start out from,
* compiler devs have to do some work for what is supposed to be dead code and just a sanity check,
* the target audience is other compiler devs.

Remove outdated Firefox-specific CSS for search's crate selector appearance
Remove adjustments that used to be necessary for search's crate selector appearance (padding) to look identical on Firefox. New versions of Firefox appear to have changed behavior to agree with Chrome.

rustdoc: fix position of `default` in method rendering
With the following code:
```rs
#![feature(specialization)]
pub trait A {
unsafe fn a();
}
impl A for () {
default unsafe fn a() {}
}
```
rustdoc would render the `impl` of `a` as
```rs
unsafe default fn a()
```
which is inconsistent with the actual position of `default`.
This PR fixes this issue.
Turn copy into moves during DSE.
Dead store elimination computes whether removing a direct store to an unborrowed place is allowed.
Where removing a store is allowed, writing `uninit` is too.
This means that we can use this pass to transform `copy` operands into `move` operands. This is only interesting in call terminators, so we only handle those.
Special care is taken for the `use_both(_1, _1)` case:
- moving the second argument is ok, as `_1` is not live after the call;
- moving the first argument is not, as the second argument reads `_1`.

editor/code: [DX] Use notification command links for debugger installation
This PR improves DX (developer experience) when installing the VS Code extension for the first time. When doing so and trying to debug a Rust file, we get an error notification that either CodeLLDB or C++ extension/debugger should be installed (see image below).
<div align="center">
<img src="https://github.com/rust-lang/rust-analyzer/assets/20957750/e8ebeb1e-85f4-44e2-b79f-c48cf52e5f36" alt="Rust, prompt to install debug extension">
</div>
The PR enhances the links in the given notification and upon clicking instead of opening the Web page of the extension it installs the extension immediately, without the need to leave the editor.
Note: the feature needs to be refined, maybe an "install in progress" message or something similar, I left that for you guys to decide and implement. I think it also possible to first open the sidebar, open the Extensions tab, then run the extension installation command which would make it more user-friendly.
P.S. it is also possible to open the extension's details in VS Code directly via the same links and then the user would have to manually click on the Install button - if installation is not the desired behavior.
Happy coding! 🎉
Pass `TraitEnvironment` into `layout_ty` and `const_eval`
We need to do either this or get rid of trait environment in `normalize_ty`. Let's go with this for now.
Verify that all crate sources are in sync
This ensures that rustc will not attempt to link against a cdylib as if it is a rust dylib when an rlib for the same crate is available. Previously rustc didn't actually check if any further formats of a crate which has been loaded are of the same version and if they are actually valid. This caused a cdylib to be interpreted as rust dylib as soon as the corresponding rlib was loaded. As cdylibs don't export any rust symbols, linking would fail if rustc decides to link against the cdylib rather than the rlib.
Two crates depended on the previous behavior by separately compiling a test crate as both rlib and dylib. These have been changed to capture their original spirit to the best of my ability while still working when rustc verifies that all crates are in sync. It is unlikely that build systems depend on the current behavior and in any case we are taking a lot of measures to ensure that any change to either the source or the compilation options (including crate type) results in rustc rejecting it as incompatible. We merely didn't do this check here for now obsolete perf reasons.

Use the correct span for displaying the line following a derive sugge…
`span` here is the main span of the diagnostic. In the linked issue's case, this belongs to `main.rs`. However, the line numbers (and line we are trying to display) are in `name.rs`, so using `span_to_lines` gives us the wrong `FileLines`.
Use `parts[0].span` (the span of the suggestion) here like the rest of the code does to get the right file.
Not sure if this needs a dedicated test because this fixes an existing error in the UI suite
Fixes#113844
Add tests for `--document-hidden-items` option
Since `--document-hidden-items` was greatly fixed/improved in https://github.com/rust-lang/rust/pull/113574, thought it might be worth adding some more tests for it to prevent new regressions.
As for the first commit, it allows to go from:

Properly document `lifetime_mapping` in `OpaqueTy`
Also use an `Option` to signify that the value is actually present, instead of just no captured lifetimes.
Update documentation for std::process::Command's new method
In the current documentation, it's not specified that when creating a Command, the .exe extension can be omitted for Windows executables. However, for other types of executable files like .bat or .cmd, the complete filename including the extension must be provided.
I encountered it by noticing that `Command::new("wt").spawn().unwrap()` succeeds on my machine while `Command::new("code").spawn().unwrap()` panics. Turns out VS Code's entrypoint is .cmd file.
`resolve_exe` method mentions this behaviour in [a comment](e7fda447e7/library/std/src/sys/windows/process.rs (L425)), but it makes sense to mention it at a more visible place.
I've added this clarification to the documentation, which should make it more accurate and helpful for Rust developers working on the Windows platform.
Fix rpath for libdir is specified
## What does this PR try to resolve?
When building the Rust toolchain with `--libdir=lib64`, the executable tools such as `rustc` cannot find shared libraries.
```bash
./configure --prefix=/ --libdir=lib64
DESTDIR=/tmp/rust ./x.py install
```
```
$ /tmp/rust/bin/rustc
rustc: error while loading shared libraries: librustc_driver-13f1fd1bc7f7000d.so: cannot open shared object file: No such file or directory
```
This issue is caused by the link args `-Wl,rpath` being different from `--libdir`.
```
$ readelf -d /tmp/rust/bin/rustc | grep RUNPATH
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib]
```
## How to resolve?
When setting the rpath, get it from sysroot libdir relative path.
After this patch:
```
$ readelf -d /tmp/rust/bin/rustc | grep RUNPATH
0x000000000000001d (RUNPATH) Library runpath: [$ORIGIN/../lib64]
```
On nightly, dump ICE backtraces to disk
Implement rust-lang/compiler-team#578.
When an ICE is encountered on nightly releases, the new rustc panic handler will also write the contents of the backtrace to disk. If any `delay_span_bug`s are encountered, their backtrace is also added to the file. The platform and rustc version will also be collected.
<img width="1032" alt="Screenshot 2023-03-03 at 2 13 25 PM" src="https://user-images.githubusercontent.com/1606434/222842420-8e039740-4042-4563-b31d-599677171acf.png">
The current behavior will *always* write to disk on nightly builds, regardless of whether the backtrace is printed to the terminal, unless the environment variable `RUSTC_ICE_DISK_DUMP` is set to `0`. This is a compromise and can be changed.
In `base.rs`, tweak how the CGU size interleaving works. Since #113777,
it's much more common to have multiple CGUs with identical sizes. With
the existing code these same-sized items ended up in the
opposite-to-desired order due to the stable sorting. The code now starts
with a reverse sort (like is done in `partitioning.rs`) which gives the
behaviour we want. This doesn't matter much for perf, but makes profiles
in `samply` look more like what we expect.
In `partitioning.rs`, we can use `sort_by_key` instead of
`sort_by_cached_key` because `CGU::size_estimate()` is cheap. (There is
an identical CGU sort earlier in that function that already uses
`sort_by_key`.)

Don't follow raw pointer derefs when considering method receiver candidates
In https://github.com/rust-lang/rust-analyzer/pull/15118, I enabled following raw pointer derefs when considering self type candidates. However, I also inadvertently enabled it for receiver type candidates, which is invalid and causes false positives (see new test).
Fix inline_const with interpolated block
Interpolation already worked when we had a `const $block` that wasn't a statement expr:
```
fn foo() {
let _ = const $block;
}
```
But it was failing when the const block was in statement expr position:
```
fn foo() {
const $block;
}
```
... because of a bug in a check for const items. This fixes that.

cc https://github.com/rust-lang/rust/pull/112953#issuecomment-1631354481, though I don't think this requires an FCP since it's already supported in exprs and seems to me to be fully a parser bug.
