- flags no longer function, see #44136
- adjust tests to match new behavior
- removed test issue-42875 (covered regression with --no-defaults)
- moved input-format to removed flags
- move all removed flags to bottom
- note flag removal in command help
- remove DefaultPassOption enum (now redundant with `show_coverage`)
rustdoc: Reduce number of arguments for `run_test` a bit
- rustdoc: Coalesce some `run_test` args as one `LangString` arg
- Rename `TestOptions` to `GlobalTestOptions`
- doctest: Rename `options` to `rustdoc_options`
rustdoc: Show type layout for type aliases
Fixes#91265.
At first, you might think, "Why not just click through to the aliased
type?" But, if a type alias instantiates all of the generic parameters
of the aliased type, then it can show layout info even though the
aliased type cannot (because we can't compute layout for generic types).
So, I think it's useful to show layout info for type aliases.
This is a followup of 78d4b453ad2e19d44011b26fc55c949bff5dba3d
(originally part of #83501).
Add --out-dir flag for rustdoc
part of https://github.com/rust-lang/rust/issues/91260
Add --out-dir flag for rustdoc and change the `-o` option to point to out-dir.
I'm not quite sure if it should be stable, also I'm not sure if this parameter priority is appropriate? Or should I just refuse to pass both parameters at the same time?

Rationale:
* The name was confusing.
* It was only used in one place.
* That place didn't actually need all the functionality of `get_type`;
rather, removing `get_type` makes that code clearer.
This commit removes the first of nine Clean impls on tuples, converting
it to a function instead.
The fact that these are impls causes several problems:
1. They are nameless, so it's unclear what they do.
2. It's hard to find where they're used apart from removing them and
seeing what errors occur (this applies to all Clean impls, not just
the tuple ones).
3. Rustc doesn't currently warn when impls are unused, so dead code
can accumulate easily (all Clean impls).
4. Their bodies often use tuple field indexing syntax (e.g., `self.1`)
to refer to their "arguments", which makes reading the code more
difficult.
As I noted, some of these problems apply to all Clean impls, but even
those problems are exacerbated by the tuple impls since they make
general understanding of the code harder.
Converting the impls to functions solves all four of these problems.
rustdoc: preload fonts
Follow-up from #82315.
I noticed that font loading was so slow that even when loading from local disk, we get a flash of unstyled text (FOUT) followed by a reflow when the fonts load. With this change, we reliably get the appropriate fonts in the first render pass when loading locally, and we get it some of the time when loading from a website.
This only preloads woff2 versions. According to https://caniuse.com/?search=preload and https://caniuse.com/?search=woff2, all browsers that support preload also support woff2, so this is fine; we will never load two copies of a font.
Don't preload italic font faces because they aren't used on all pages.
Demo: https://rustdoc.crud.net/jsha/preload-fonts/std/string/struct.String.html

Cleanup: Eliminate ConstnessAnd
This is almost a behaviour-free change and purely a refactoring. "almost" because we appear to be using the wrong ParamEnv somewhere already, and this is now exposed by failing a test using the unstable `~const` feature.
We most definitely need to review all `without_const` and at some point should probably get rid of many of them by using `TraitPredicate` instead of `TraitRef`.
This is a continuation of https://github.com/rust-lang/rust/pull/90274.
