feat: add backtick to surrounding and auto-closing pairs
Makes backticks always complete as a pair and also surround the current selection, similar to double quotes. This is useful primarily in the context of markdown doc comments, but is applied globally for simplicity.

core library: Disable fpmath tests for i586 ...
This patch disables the floating-point epsilon test for i586 since x87 registers are too imprecise and can't produce the expected results.
vscode: Fix line and col regexp for `rustc` problem matcher
When building the Rust compiler with `./x check` from within VS Code, the current `rustc` problem matcher thinks that the output from that command that looks like this:
Build completed successfully in 0:00:26
is about a problem in a file named `0` on line 00, col 26. This wouldn't be so bad if it wasn't for that VS Code tends to get stuck on this problem because of problems with opening the file '0'.
The rust compiler will never output problems with a line or a column that starts with 0, so change the regexp to require lines and cols to begin with `[1-9]` to fix this problem.
Improve UdpSocket documentation
I tried working with `UdpSocket` and ran into `EINVAL` errors with no clear indication of what causes the error. Also, it was uncharacteristically hard to figure this module out, compared to other Rust `std` modules.
1. `send` and `send_to` return a `usize` This one is just clarity. Usually, returned `usize`s indicate that the buffer might have only been sent partially. This is not the case with UDP. Since that `usize` must always be `buffer.len()`, I have documented that.
2. `bind` limits `connect` and `send_to` When you bind to a limited address space like localhost, you can only `connect` to addresses in that same address space. Error kind: `AddrNotAvailable`.
3. `connect`ing to localhost locks you to localhost On Linux, if you first `connect` to localhost, subsequent `connect`s to
non-localhost addresses fail. Error kind: `InvalidInput`.
For debugging the third one, it was really hard to find someone else who already had that problem. I only managed to find this thread: https://www.mail-archive.com/netdev@vger.kernel.org/msg159519.html
fix: allow more kinds of if let patterns in guarded return assist
Removes the checks that require the pattern to be a tuple struct with exactly 1 field that is unqualified and has an identifier pattern in it. I'm not sure if there should be more checks in place but they seem unnecessary now?
Closes#15695
bootstrap major change detection implementation
The use of `changelog-seen` and `bootstrap/CHANGELOG.md` has not been functional in any way for many years. We often do major/breaking changes but never update the changelog file or the `changelog-seen`. This is an alternative method for tracking major or breaking changes and informing developers when such changes occur.
Example output when bootstrap detects a major change:
Partially outline code inside the panic! macro
This outlines code inside the panic! macro in some cases. This is split out from https://github.com/rust-lang/rust/pull/115562 to exclude changes to rustc.
Prototype using const generic for simd_shuffle IDX array
cc https://github.com/rust-lang/rust/issues/85229
r? `@workingjubilee` on the design
TLDR: there is now a `fn simd_shuffle_generic<T, U, const IDX: &'static [u32]>(x: T, y: T) -> U;` intrinsic that allows replacing
```rust
simd_shuffle(a, b, const { stuff })
```
with
```rust
simd_shuffle_generic::<_, _, {&stuff}>(a, b)
```
which makes the compiler implementations much simpler, if we manage to at some point eliminate `simd_shuffle`.
There are some issues with this today though (can't do math without bubbling it up in the generic arguments). With this change, we can start porting the simple cases and get better data on the others.
stabilize combining +bundle and +whole-archive link modifiers
Per discussion on https://github.com/rust-lang/rust/issues/108081 combining +bundle and +whole-archive already works and can be stabilized independently of other aspects of the packed_bundled_libs feature. There is no risk of regression because this was not previously allowed.

Only run tests on linux in pull requests
There is little gain from running them on all platforms, they should almost never fail if the linux one pass and if they do, bors will catch it still.
