Replacing the UnsafeCell by a Cell simplifies things and makes it all safe.

This also allows 'rustdoc' as a string for the compiler profile.

Fixes rust-lang#55890 It's useful to have `llc` and `opt` available when debugging an LLVM miscompilation,.
Modern compilers allow reaching external crates like std or core via relative paths in modules outside of lib.rs and main.rs.
…oalbini Enable building Cargo for aarch64-apple-darwin r? @ghost
…ulacrum BTreeMap: type-specific variants of node_as_mut and cast_unchecked Improves debug checking and shortens some expressions. Extracted from rust-lang#77408
…mutex-attr-cleanup, r=Mark-Simulacrum Remove unnecessary rustc_const_stable attributes. These attributes were added in rust-lang#74033 (comment) because of [std::io::lazy::Lazy::new](https://github.com/rust-lang/rust/blob/0c03aee8b81185d65b5821518661c30ecdb42de5/src/libstd/io/lazy.rs#L21-L23). But [std::io::lazy::Lazy is gone now](rust-lang#77154), so this can be cleaned up. @rustbot modify labels: +T-libs +C-cleanup
…ported-locks, r=Mark-Simulacrum 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. @rustbot modify labels: +F-unsafe-block-in-unsafe-fn +C-cleanup
…-Simulacrum Add regression issue template Feel free to suggest improvements!
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. r? @Mark-Simulacrum Closes rust-lang#77711
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. r? @Mark-Simulacrum
…stic, r=lcnr `min_const_generics` diagnostics improvements As disscussed in [zulip/project-const-generics/non-trivial anonymous constant](https://rust-lang.zulipchat.com/#narrow/stream/260443-project-const-generics/topic/non-trivial.20anonymous.20constants). This is my first PR on the compiler. @lcnr is mentoring me on this PR. Related to rust-lang#60551.
…k-Simulacrum Include `llvm-dis`, `llc` and `opt` in `llvm-tools-preview` component Fixes rust-lang#55890 It's useful to have `llc` and `opt` available when debugging an LLVM miscompilation,.
Use Option::unwrap_or instead of open-coding it
…petrochenkov 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.
…hs, r=lcnr 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.
…roalbini Include aarch64-apple-darwin in the dist manifests r? @ehuss /cc @pietroalbini @Mark-Simulacrum

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
```
