Implement uncommon_codepoints lint.
Part of #55467 . The checks of `$crate` and `{{root}}` are very unfortunate. But i'm not sure where they belongs to.
Nix reexports from `rustc_span` in `syntax`
Remove reexports `syntax::{source_map, symbol, edition}` and use `rustc_span` paths directly.

Teach `compiletest` to ignore platform triples
The UI tests are written assuming `--remap-path-prefix` is *not used* (`remap-debuginfo` in `config.toml`). The consequence is that the error messages may include paths and snippets into the standard library. When `remap-debuginfo` is enabled, these messages change in format and structure because `rustc` will not show paths and snippets into the standard library.
This normally isn't a problem for the "main" platforms (linux/macos/windows), because the CI infrastructure is set up so that the tests run without `remap-debuginfo`, but the `dist` artifacts are built separately with `remap-debuginfo` enabled. However, some of the lower-tier platforms perform both tests and distribution in a single step with `remap-debuginfo` enabled. This also affects developers and distributors who use `remap-debuginfo`.
To sidestep this problem, we add a way to ignore tests in specific platform triples, and update the overly broad `ignore-x86` rule in affected tests.
Address #46948, #54546, #53081.
Deprecate Error::description for real
`description` has been documented as soft-deprecated since 1.27.0 (17 months ago). There is no longer any reason to call it or implement it.
This PR:
- adds `#[rustc_deprecated(since = "1.41.0")]` to `Error::description`;
- moves `description` (and `cause`, which is also deprecated) below the `source` and `backtrace` methods in the Error trait;
- reduces documentation of `description` and `cause` to take up much less vertical real estate in rustdocs, while preserving the example that shows how to render errors without needing to call `description`;
- removes the description function of all *currently unstable* Error impls in the standard library;
- marks `#[allow(deprecated)]` the description function of all *stable* Error impls in the standard library;
- replaces miscellaneous uses of `description` in example code and the compiler.

Require issue = "none" over issue = "0" in unstable attributes
These changes make the use of `issue = "none"` required in unstable attributes throughout the compiler.
Notes:
- #66299 is now in beta so `issue = "none"` is accepted.
- The `tidy` tool now fails on `issue = "0"`.
- Tests that used `issue = "0"` were changed to use `issue = "none"`, except for _one_ that asserts `issue = "0"` can still be used.
- The compiler still allows `issue = "0"` because some submodules require it, this could be disallowed once these are updated.
Resolves#41260

Revamp `// run-fail` wrt. `--pass` & support `// build-fail` & `// check-fail`
Revamp how `// run-fail` tests work internally by having a separate `FailMode` that does not interfere with `PassMode`. In particular, `--pass check` will now have no effect on `// *-fail` tests. Moreover, new test annotations `// check-fail` (the default) and `// build-fail` are added. The latter is useful to distinguish post-monomorphization failures from pre-monomorphization failures as seen throughout the PR. Finally, ensure that non-`Ui` tests do not listen to `--pass check` such that the flag can be used with e.g. `./x.py test --pass check` directly.
Fixes#66929.
Fixes#67128.

- Fix `impl Gpio` -> `impl GpioConfig` (rust-embedded/book#216)
It was already filtered from other branches, but we only kept it in
nightly's default to ease the transition. Now that the separation of
rust-std/rustc-dev has reached the 1.40 release, it seems like a good
time for that transition to end.
