Yuki Okushi 0af50b4d32 Rollup merge of #87385 - Aaron1011:final-enable-semi, r=petrochenkov
Make `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` warn by default

This PR makes the `SEMICOLON_IN_EXPRESSIONS_FROM_MACROS` lint warn by default.

To avoid showing a large number of un-actionable warnings to users, we only enable the lint for macros defined in the same crate. This ensures that users will be able to fix the warning by simply removing a semicolon.

In the future, I'd like to enable this lint unconditionally, and eventually make it into a hard error in a future edition. This PR is a step towards that goal.

Implement `x.py test src/tools/clippy --bless`

- Add clippy_dev to the rust workspace

  Before, it would give an error that it wasn't either included or
  excluded from the workspace:

  ```
  error: current package believes it's in a workspace when it's not:
  current:   /home/joshua/rustc/src/tools/clippy/clippy_dev/Cargo.toml
  workspace: /home/joshua/rustc/Cargo.toml

  this may be fixable by adding `src/tools/clippy/clippy_dev` to the `workspace.members` array of the manifest located at: /home/joshua/rustc/Cargo.toml
  Alternatively, to keep it out of the workspace, add the package to the `workspace.exclude` array, or add an empty `[workspace]` table to the package's manifest.
  ```

- Change clippy's copy of compiletest not to special-case
  rust-lang/rust. Using OUT_DIR confused `clippy_dev` and it couldn't find
  the test outputs. This is one of the reasons why `cargo dev bless` used
  to silently do nothing (the others were that `CARGO_TARGET_DIR` and
  `PROFILE` weren't set appropriately).

- Run clippy_dev on test failure

I tested this by removing a couple lines from a stderr file, and they
were correctly replaced.

Add `Unsupported` to `std::io::ErrorKind`

I noticed a significant portion of the uses of `ErrorKind::Other` in std is for unsupported operations.
The notion that a specific operation is not available on a target (and will thus never succeed) seems semantically distinct enough from just "an unspecified error occurred", which is why I am proposing to add the variant `Unsupported` to `std::io::ErrorKind`.

**Implementation**:

The following variant will be added to `std::io::ErrorKind`:

```rust
/// This operation is unsupported on this platform.
Unsupported
```
`std::io::ErrorKind::Unsupported` is an error returned when a given operation is not supported on a platform, and will thus never succeed; there is no way for the software to recover. It will be used instead of `Other` where appropriate, e.g. on wasm for file and network operations.

`decode_error_kind` will be updated  to decode operating system errors to `Unsupported`:
- Unix and VxWorks: `libc::ENOSYS`
- Windows: `c::ERROR_CALL_NOT_IMPLEMENTED`
- WASI: `wasi::ERRNO_NOSYS`

**Stability**:
This changes the kind of error returned by some functions on some platforms, which I think is not covered by the stability guarantees of the std? User code could depend on this behavior, expecting `ErrorKind::Other`, however the docs already mention:

> Errors that are `Other` now may move to a different or a new `ErrorKind` variant in the future. It is not recommended to match an error against `Other` and to expect any additional characteristics, e.g., a specific `Error::raw_os_error` return value.

The most recent variant added to `ErrorKind` was `UnexpectedEof` in `1.6.0` (almost 5 years ago), but `ErrorKind` is marked as `#[non_exhaustive]` and the docs warn about exhaustively matching on it, so adding a new variant per se should not be a breaking change.

The variant `Unsupported` itself could be marked as `#[unstable]`, however, because this PR also immediately uses this new variant and changes the errors returned by functions I'm inclined to agree with the others in this thread that the variant should be insta-stabilized.

Ömer Sinan Ağacan ce4e668e39 format macro argument parsing fix
When the character next to `{}` is "shifted" (when mapping a byte index
in the format string to span) we should avoid shifting the span end
index, so first map the index of `}` to span, then bump the span,
instead of first mapping the next byte index to a span (which causes
bumping the end span too much).

Regression test added.
