RFC 2457 [declares](121bbeff50/text/2457-non-ascii-idents.md): "A `non_ascii_idents` lint is added to the compiler. This lint is allow by default."
(Part of #55467.)

name the trait in ambiguous-associated-items fully qualified suggestion
We have the trait at this point, so we can name it in the error message, rather than using "Trait" as a (potentially confusing) placeholder.
Thanks to Yuki "@JohnTitor" Okushi for pointing out where to look (in the same file) for a closely related issue for ambiguous associated types (as opposed to items; that was #59225, except that one won't be
quite as easy to resolve, because we actually don't have the trait `DefId` at that point).

rustbuild: Cleanup global lint settings
Lint settings do not depend on `if let Some(target) = target` in any way, so they are moved out of that clause.
Internal lints now respect `RUSTC_DENY_WARNINGS`.
Crate name treatment is cleaned up a bit.

First question mark in doctest
We have had `?` for `Result`s in doctests for some time, but so far haven't used them in doctests. With this PR, I want to start the de-`unwrap`ping of doctests – and the discussion on where to do so.
There is one downside, which is that the code can no longer be copied into a plain `main()` method, on the other hand, there should be a workable error if one does this.
Now that procedural macros no longer link transitively to libsyntax,
this shouldn't be needed any more! This commit is an experiment in
removing all dynamic libraries from rustc except for librustc_driver
itself. Let's see how far we can get with that!
We have the trait at this point, so we can name it in the error
message, rather than using "Trait" as a (potentially confusing)

Improve documentation for built-in macros
This is the `libcore` part of https://github.com/rust-lang/rust/pull/62086.
Right now the only effect is improved documentation.
The changes in the last few commits are required to make the `libcore` change compile successfully.
