suggestion for typoed crate or module
Previously, the compiler didn't suggest similarly named crates or modules. This pull request adds a suggestion for typoed crates or modules.
#76208
before:
```
error[E0433]: failed to resolve: use of undeclared type or module `chono`
--> src/main.rs:2:5
|
2 | use chono::prelude::*;
| ^^^^^ use of undeclared type or module `chono`
```
after:
```
error[E0433]: failed to resolve: use of undeclared type or module `chono`
--> src/main.rs:2:5
|
2 | use chono::prelude::*;
| ^^^^^
| |
| use of undeclared crate or module `chono`
| help: a similar crate or module exists: `chrono`
```
Remove textual span from diagnostic string
This is an unnecessary repetition, as the diagnostic prints the span anyway in the source path right below the message.
I further removed the identification of the node, as that does not give any new information in any of the cases that are changed in tests.
EDIT: also inserted a suggestion that other diagnostics were already emitting
fix the stage0 tools config file path in `config.toml.example`
in #88362 , the `stage0.txt ` have been switched to `stage0.json` , but in `config.toml.example` the guide didn't change , this PR fix this issue
Fix config.toml overflow-checks options
This a follow-up PR to #87784.
Improvements:
* Add missing entries for overflow-checks to config.toml.example.
* Add --enable-overflow-checks-std option to configure script.
* Make rust.overflow-checks-stdoption default to rust.overflow-checks.
Also adds the missing `--enable-debug-assertions-std `option to configure script.

Fix invalid rules in .gitignore
`**node_modules` in a .gitignore is the same than
`*node_modules` or `*****node_modules`.
It matches every file whose name ends with `node_modules`,
including `not_node_modules`.
The intent here was obviously to have `**/node_modules`
which is the same than just `node_modules`.

Improve CJK font in rustdoc
This PR includes:

add some more testcases

All these issues have been fixed according to glacier. Just adding a test so it can be closed.
Can anybody tell me why the github keywords do not work? 🤔
Please edit this post if you can fix it.
Include rmeta candidates in "multiple matching crates" error
Only dylib and rlib candidates were included in the error. I think the
reason is that at the time this error was originally implemented, rmeta
crate sources were represented different from dylib and rlib sources.
I wrote up more detailed analysis in [this comment][1].
The new version of the code is also a bit easier to read and should be
more robust to future changes since it uses `CrateSources::paths()`.
I also changed the code to sort the candidates to make the output deterministic;
added full stderr tests for the error; and added a long error code explanation.

Previously, there was no way to actually get binaries in
`build/$TARGET/stage1/bin` without building the standard library. This
makes it possible to build just the compiler. This can be useful when
the standard library isn't actually necessary for trying out your tests
(e.g. a bug that can be reproduced with only a `no_core` crate).
avoid suggesting the same name
sort candidates
fix a message
use `opt_def_id` instead of `def_id`
move `find_similarly_named_module_or_crate` to rustc_resolve/src/diagnostics.rs

Fix: non_exhaustive_omitted_patterns by filtering unstable and doc hidden variants
Fixes: #89042
Now that #86809 has been merged there are cases (std::io::ErrorKind) where unstable feature gated variants were included in warning/error messages when the feature was not turned on. This filters those variants out of the return of `SplitWildcard::new`.
Variants marked `doc(hidden)` are filtered out of the witnesses list in `Usefulness::apply_constructor`.
Probably worth a perf run 🤷 since this area can be sensitive.
The test is copied from `src/test/ui/crate-loading/crateresolve1.rs` and
its auxiliary tests. I added it to the `compile_fail` code example check
exemption list since it's hard if not impossible to reproduce this error
in a standalone code example.
Only dylib and rlib candidates were included in the error. I think the
reason is that at the time this error was originally implemented, rmeta
