bootstrap: set correct path for the build-manifest binary
This changes the path of the binary inside the tarball to be:
```
build-manifest-{release}-{target}/build-manifest/bin/build-manifest
```
...instead of:
```
build-manifest-{release}-{target}/build-manifest/bin/build-manifest/build-manifest
```

Replace absolute paths with relative ones
Modern compilers allow reaching external crates
like std or core via relative paths in modules
outside of lib.rs and main.rs.
Replace trivial bool matches with the `matches!` macro
This derives `PartialEq` on one enum (and two structs it contains) to enable the `==` operator for it. If there's some downside to this, I could respin with the `matches!` macro instead.
Include `llvm-dis`, `llc` and `opt` in `llvm-tools-preview` component
Fixes#55890
It's useful to have `llc` and `opt` available when debugging an LLVM
miscompilation,.
Mention rustdoc in `x.py setup`
This lets new contributors know which option they should pick; previously it wasn't clear 'compiler' also included rustdoc.
Unresolved questions: should this say 'compiler and tools' instead? I don't know of any tools that are modified in-tree other than rustdoc, though.

Give an error when running `x.py test --stage 0 src/test/ui`
The error can be overridden with `COMPILETEST_FORCE_STAGE0=1`. In practice I don't know why anyone would do this.

Closes https://github.com/rust-lang/rust/issues/77711
Remove unsafety from sys/unsupported and add deny(unsafe_op_in_unsafe_fn).
Replacing `UnsafeCell`s by a `Cell`s simplifies things and makes the mutex and rwlock implementations safe. Other than that, only unsafety in strlen() contained unsafe code.

[generator] Special cases for match guard when analyzing interior types in generators
Fix#72651
This proposes one of ways to fix the mentioned issue. One cause of #72651 is that the interior type analysis misses out types of match pattern locals. Those locals are manifested as temporary borrows in the scopes of match arm guards. If uses of these locals appear after yield points, the borrows from them were not considered live across the yield points. However, this is not the case since the borrowing always happens at the very beginning of the match guard.
This calls for special treatment to analysis of types appearing in the match guard. Those borrows are recorded as the HIR tree is walked by `InteriorVisitor` and their uses are recorded whenever a yield point is crossed.
Certain platforms need to limit the DWARF version emitted (oxs, *bsd). This
change adds a dwarf_version entry to the options that allows a platform to
specify the dwarf version to use. By default this option is none and the default
DWARF version is selected.
Also adds an option for printing Option<u32> json keys
Dist build manifest
This PR makes two changes that should remove a significant chunk of the time spent in our release process: cloning the `rust-lang/rust` monorepo, all its submodules, and building `bootstrap` to then invoke `build-manifest`:
* `build-manifest` doesn't rely on a clone of the monorepo being present anymore. The only remaining bit of information it fetched from it (the Rust version) is instead bundled in the binary.
* A new "component" is added, `build-manifest`. That component includes a prebuilt version of the tool, and it's *not* included in the Rustup manifest. This will allow `promote-release` to directly invoke the tool without interacting with our build system.
* The Linux x86_64 CI is changed to also build the component mentioned above. It's the only CI builder tasked to do so, and to cleanly support this a new `--include-default-paths` flag was added to `./x.py`.
* The `BUILD_MANIFEST_NUM_THREADS` environment variable is added to configure the number of threads at runtime.
This PR is best reviewed commit-by-commit.
