When two multiline span labels point at the same span, we special
case the output to avoid weird behavior:
```
foo(
_____^
|_____|
|| bar,
|| );
|| ^
||______|
|______foo
baz
```
instead showing
```
foo(
_____^
| bar,
| );
| ^
| |
|______foo
baz
```
`-Z treat-err-as-bug=0` will cause `rustc` to panic after the first
error is reported. `-Z treat-err-as-bug=2` will cause `rustc` to
panic after 3 errors have been reported.
Hidden suggestion support
Add way to hide suggestion snippet window from cli output to avoid cluttered spans that don't enhance understanding.

Cosmetic improvements to doc comments
This has been factored out from https://github.com/rust-lang/rust/pull/58036 to only include changes to documentation comments (throughout the rustc codebase).

Once you're happy with this, maybe we could get it through with r=1, so it doesn't constantly get invalidated? (I'm not sure this will be an issue, but just in case...) Anyway, thanks for your advice so far!
Deduplicate mismatched delimiter errors
Delay unmatched delimiter errors until after the parser has run to deduplicate them when parsing and attempt recovering intelligently.
Second attempt at #54029, follow up to #53949. Fix#31528.
The emitter already verifies wether a given span note or span label
can be emitted to the output. If it can't, because it is a dummy
span, it will be either elided for labels or emitted as an unspanned
note/help when applicable.
add applicability to remaining suggestions
Fixes#50723.
I noticed that the suggestion methods on `DiagnosticBuilder` weren't actually deprecated due to #57679. This PR deprecates them properly and fixes the remaining usages.
There's also a PR for clippy at rust-lang/rust-clippy#3667.
* Update bootstrap compiler
* Update version to 1.33.0
* Remove some `#[cfg(stage0)]` annotations
Actually updating the version number is blocked on updating Cargo
Replace usages of `..i + 1` ranges with `..=i`.
Before this change we were using old computer code techniques. After this change we use the new and improved computer code techniques.
