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.

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.

…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.

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.

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.

`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.

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

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.

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
```
