Allow allow enums like `Result<T, E>` to be used across FFI if the T/E can be niche optimized and the non-niche-optimized type is FFI safe.
Fields are disallowed so checking the top attribute is enough.
Couldn't find documentation supporting that single-variant
`#[repr(Rust)]` enums with RHS assigned work as expected with this
change.
```rust
enum Variants {
A = 17,
} // Would this be zero sized optimized guaranteed?
```
Add `rustfmt` cfg to well known cfgs list This PR adds the `rustfmt` cfg to the well known cfgs list. Related to rust-lang#124735
Support Result<T, E> across FFI when niche optimization can be used (v2) This PR is identical to rust-lang#122253, which was approved and merged but then removed from master by a force-push due to a [CI bug](https://rust-lang.zulipchat.com/#narrow/stream/242791-t-infra/topic/ci.20broken.3F). r? ghost Original PR description: --- Allow allow enums like `Result<T, E>` to be used across FFI if the T/E can be niche optimized and the non-niche-optimized type is FFI safe. Implementation of rust-lang/rfcs#3391 Tracking issue: rust-lang#110503 Additional ABI and codegen tests were added in rust-lang#115372
…erminism, r=jieyouxu Migrate `run-make/rustdoc-error-lines` to new `rmake.rs` Part of rust-lang#121876. There was a weird naming inconsistency with `input`/`output`. A few tests write `.arg("-o").arg(path)` and the `output` method was actually the command output. So instead, I renamed the original `output` into `command_output` so that I could create the `output` method with the expected effect (and updated the tests to use it too). EDIT: The first two commits come from rust-lang#124711. Some weird things happened recently pparently. ^^' r? `@jieyouxu`
