Make the lifetime accurate which is used in the region constraints part
This PR fixes the FIXME about lifetime using in the region constraints part.
We cannot write `<'graph, 'tcx, D>` because the definition of `Successors<'0, '1, D>` requires `'1 : '0`.
We cannot add bound to `'graph` either because `'graph` is required to be an arbitrary value in the definition of `WithSuccessors`
So the most accurate way is to use `<'s, 'tcx, D>`.

Update `validate_uninhabited_zsts.rs` test after MIR building changes
to ensure that it still tests validation, instead of failing earlier on
during evaluation.
r? `@RalfJung`
The self-profiler's `EventArgRecorder` is general-purpose in its ability to record Strings (and `rustc_span` depends on the crate its defined in, `rustc_data_structure`).
Some generic activities could use recording locations where they happen in the user's code: to allow e.g. to track macro expansions and diagnose performance issues there.
This adds a `SpannedEventArgRecorder` that can record an argument given as a span, rather than a String, since turning spans into Strings can be tricky if you're not happy with its default Debug output. This way the recorder can have a `record_arg_spanned` method which will do that.
Make all thir types implement clone
This PR adds `Clone` impl to all of the `Thir<'tcx>` types.
I would like to be able to clone a `Thir` body so that I can make a copy in my rustc driver without breaking further compilation. Without this my driver is forced to run in the `after_expansion` callback and thus doesn't benefit from running all the safety checks that `rustc` usually does, instead i need to do them all myself.
Ensure existance of dist directory when creating tarball
I'm not sure why this works in CI, but this is necessary to make distcheck (including the `x86_64-linux-distcheck` image) run on Fedora 35.
This is not super important to do, but the consistency is nice.
I didn't change any tests that call `configure("dist")` and then override the subcommand - doing
that at all is pretty sketchy, but I don't want to mess with it while already doing a refactor.
I didn't know that the `test::` syntax was valid before, and it doesn't
seem to be documented anywhere. Add a test so it doesn't regress accidentally,
and as executable documentation.
rustdoc: Unindent doc fragments on `Attributes` construction
`Attributes` can be constructed at arbitrary points, even after the `unindent_comments` pass.
`Attributes` that are constructed too late end up unindented.
All doc fragments need to be eventually indented before use, so there are no reasons to not do this immediately during their construction.
Fixes https://rust-lang.zulipchat.com/#narrow/stream/266220-rustdoc/topic/.60unindent_comments.60.20cannot.20work.20as.20a.20separate.20pass.
I'm not sure how to make a minimized reproduction, but unindenting the fragments during their construction should fix the issue.. by construction, and I also verified that all doc strings now hit the `resolver_caches.markdown_links` cache in https://github.com/rust-lang/rust/pull/94857.
errors: minor translation-related changes
- For one error in typeck, specifying "suggestion" as the attribute for the only suggestion is unnecessary, it's the default of the derive.
- The documentation comment for the `SessionDiagnostic` derive is out-of-date, it should have been updated in #95512.

Only output DepKind in dump-dep-graph.
When printing the whole DepNode, the output file is simply too massive to
be actually useful for profiling.
This trimmed down version mixes a lot of information together, but it also
allows to ask questions such that "why does this query ever access HIR?".
bootstrap: consolidate subcommand parsing and matching
There's several places where the x.py command names are matched as
strings, leading to some inconsistencies and opportunities for cleanup.
* Add Format, Clean, and Setup variants to builder::Kind.
* Use Kind to parse the x.py subcommand name (including aliases)
* Match on the subcommand Kind rather than strings when handling
options and help text.
* Several subcommands don't display any paths when run with `-h -v` even
though the help text indicates that they should. Fix this and refactor
so that manually keeping matches in sync isn't necessary.
Fixes#95937
bootstrap: add split-debuginfo config
Replace `run-dysutil` option with more general `split-debuginfo` option that works on all platforms.
r? `@Mark-Simulacrum`
This lets us clone just the parts within a `TokenTree` that need
cloning, rather than the entire thing. This is a surprisingly large
performance win, up to 4% on `async-std-1.10.0`.
Specifying "suggestion" as the attribute for the only suggestion is
unnecessary, it's the default of the derive.

This makes `CloseDelim` handling more like `OpenDelim` handling, which
produces `OpenDelim` and pushes the stack at the same time. It requires
some adjustment to `parse_token_tree` now that we don't remain within
the frame after getting the `CloseDelim`.
