These methods work very similarly to `Option`'s methods `as_ref` and
`as_mut`. They are useful in several situation, particularly when
calling other array methods (like `map`) on the result. Unfortunately,
we can't easily call them `as_ref` and `as_mut` as that would shadow
those methods on slices, thus being a breaking change (that is likely
to affect a lot of code).

rustdoc: Remove `*` intra-doc alias for `pointer`
It's not valid Rust code and it can easily be confused with a wildcard
glob pattern or something else. People can always use `pointer` instead,
so it's just removing an alias.
It hasn't hit stable yet (I think it's still on nightly), so it's okay
to remove it. (We can always add it back later if we change our mind
too.)

log-color: Detect TTY based on stderr, not stdout
Fixes#78435 (again).
Logging goes to stderr, not stdout, so we should base our automated
detection on stderr instead of stdout.
Thanks to Ralf Jung for noticing and reporting the bug!

Add ABI argument to `find_mir_or_eval_fn`
Add ABI argument for called function in `find_mir_or_eval_fn` and
`call_extra_fn`. Useful for comparing with expected ABI in interpreters.

Use standard formatting for "rust-call" ABI message
Nearly all error messages start with a lowercase letter and don't use
articles - instead they refer to the plural case.
Don't build in-tree llvm-libunwind if system-llvm-libunwind is enable
When "system-llvm-libunwind" is enabled, some target eg. musl still build in-tree llvm-libunwind which is useless.

resolve: Scope visiting doesn't need an `Ident`
Resolution scope visitor (`fn visit_scopes`) currently takes an `Ident` parameter, but it doesn't need a full identifier, or even its span, it only needs the `SyntaxContext` part.
The `SyntaxContext` part is necessary because scope visitor has to jump to macro definition sites, so it has to be directed by macro expansion information somehow.
I think it's clearer to pass only the necessary part.
Yes, usually visiting happens as a part of an identifier resolution, but in cases like collecting traits in scope (#80765) or collecting typo suggestions that's not the case.

Logging goes to stderr, not stdout, so we should base our automated

Thanks to Ralf Jung for noticing and reporting the bug!
People almost always are referring to `&str`, not `str`, so this will
save a manual link resolve in many cases.
Note that we already accept `&` (resolves to `reference`) in intra-doc
links, so this shouldn't cause breakage.

BTreeMap: tougher checking on most uses of copy_nonoverlapping
Miri checks pointer provenance and destination, but we can check it in debug builds already.
Also, we can let Miri confirm we don't mistake imprints of moved keys and values as genuine.

Allow #[rustc_builtin_macro = "name"]
This adds the option of specifying the name of a builtin macro in the `#[rustc_builtin_macro]` attribute: `#[rustc_builtin_macro = "name"]`.
This makes it possible to have both `std::panic!` and `core::panic!` as a builtin macro, by using different builtin macro names for each. This is needed to implement the edition-specific behaviour of the panic macros of RFC 3007.
Also removes `SyntaxExtension::is_derive_copy`, as the macro name (e.g. `sym::Copy`) is now tracked and provides that information directly.

Remove under-used ImplPolarity enum
It doesn't make much sense to have an enum with only two possible values and to store it inside an `Option` in my opinion when you can do all the same with a simple boolean. I don't expect any chances, performance or RSS usage wise.

Support `download-ci-llvm` on NixOS
In particular, the CI built `libLLVM-*.so` needs to have `libz.so`
RPATHed so that binaries like `llvm-config` work at all.
