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.

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`.
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`.

Add an explicit `Span` field to `OutlivesConstraint`
Previously, we would retrieve the span from the `Body` using
the `locations` field. However, we may end up changing the
`locations` field when moving a constraint from a promoted
to a different body.
We now store the original `Span` in a dedication field, so that
changes to the `locations` do not affect the quality of our
diagnostics.
Remove assertion that all paths in `ShouldRun` exist
This breaks on submodules (see #96188). Disable the assertion for now until I can think of a proper
fix.
This doesn't revert any of the changes in `Step`s themselves, only what
`ShouldRun::paths` does.
[fuchsia] Add implementation for `current_exe`
This implementation returns a best attempt at the current exe path. On
fuchsia, fdio will always use `argv[0]` as the process name and if it is
not set then an error will be returned. Because this is not guaranteed
to be the case, this implementation returns an error if `argv` does not
contain any elements.
Create real parser for search queries
You can test it [here](https://rustdoc.crud.net/imperio/improve-rustdoc-search/std/index.html).
This PR adds a real parser for the query engine in rustdoc. The parser is quite simple but it allows to makes query handling much easier. I added a new testsuite to ensure it works as expected and ran fuzzing checks on it for a few hours without problems.
So about the parser: as you can see in the screenshot, it handles recursive generics parsing. It also allows to set which item should use exact matching by adding double-quotes around it (look for `exact_search` in the screenshot).
Now about the query engine itself: I simplified it a lot thanks to the parsed query. It behaves mostly the same when there is only one argument, but is much more powerful when there are more than one.
When making this change, we also removed the support for multi-query.
PS: A big part of the PR is tests and test-related code. :)

remove_dir_all_recursive: treat ELOOP the same as ENOTDIR
On older Linux kernels (I tested on 4.4, corresponding to Ubuntu 16.04), opening a symlink using `O_DIRECTORY | O_NOFOLLOW` returns `ELOOP` instead of `ENOTDIR`. We should handle it the same, since a symlink is still not a directory and needs to be `unlink`ed.
Use sys::unix::locks::futex* on wasm+atomics.
This removes the wasm-specific lock implementations and instead re-uses the implementations from sys::unix.

Improve AddrParseError description
The existing description was incorrect for socket addresses, and misleading: users would see “invalid IP address syntax” and suppose they were supposed to provide an IP address rather than a socket address.
I contemplated making it two variants (IP, socket), but realised we can do still better for the IPv4 and IPv6 types, so here it is as six.
I contemplated more precise error descriptions (e.g. “invalid IPv6 socket address syntax: expected a decimal scope ID after %”), but that’s a more invasive change, and probably not worthwhile anyway.
Check if call return type is visibly uninhabited when building MIR
The main motivation behind the change is to expose information about diverging
calls to the generator transform and match the precision of drop range tracking
which already understands that call expressions with visibly uninhabited types
diverges.
This change should also accept strictly more programs than before. That is
programs that were previously rejected due to errors raised by control-flow
sensitive checks in a code that is no longer considered reachable.
Fixes#93161.

A Google search of the error message fails to return any relevant
resuts, suggesting this has never occurred in practice. And removeing it
reduces instruction counts by up to 2% on some benchmarks.
Previously, we would retrieve the span from the `Body` using
the `locations` field. However, we may end up changing the
`locations` field when moving a constraint from a promoted
to a different body.
We now store the original `Span` in a dedication field, so that
changes to the `locations` do not affect the quality of our
diagnostics.
The loop is there to handle a `NoDelim` open/close token. This commit
changes `TokenCursor::inlined_next` so it never returns such a token.
This is a performance win because the conditional test in `bump()` is
removed.
If the parser needs changing in the future to handle `NoDelim` tokens,
then `inlined_next()` can easily be changed to return them.
The `DelimToken` here is `NoDelim`, which means the returned delim
tokens will just be ignored by `Parser::bump()`. This commit changes
things so the delim tokens won't be returned.
Temporarily, only enable split debuginfo on Windows if not building with
the boostrap compiler as there is a bug that isn't fixed in the
bootstrap compiler which would result in `thorin` being run on Windows.

Miri provenance cleanup
Reviewing https://github.com/rust-lang/rust/pull/95826 by ``@carbotaniuman`` made me realize that we could clean things up a little here.
``@carbotaniuman`` please let me know if you're okay with landing this (it will create a lot of conflicts with your PR), or if you'd prefer incorporating the ideas from this PR into yours. I think we want to end up in a situation where the function you called `ptr_reify_alloc` returns just two things, a concrete tag and an offset. Getting an `AllocId` from a concrete tag should be infallible like now. However a concrete tag and `Tag` don't have to be the same type.
