Rollup merge of #95370 - jyn514:less-verbose-skips, r=Dylan-DPC
[bootstrap] Don't print `Suite not skipped` unless `--verbose` is set

This was so verbose before that it made it hard to see what effect the flag actually had.

Before:
```
Set({test::src/tools/tidy}) not skipped for "bootstrap::test::Tidy" -- not in [src/test/ui, src/test/mir-opt/, src/test/debuginfo, src/test/ui-fulldeps]
Skipping Suite(test::src/test/ui) because it is excluded
Suite(test::src/test/run-pass-valgrind) not skipped for "bootstrap::test::RunPassValgrind" -- not in [src/test/ui, src/test/mir-opt/, src/test/debuginfo, src/test/ui-fulldeps]
Skipping Suite(test::src/test/mir-opt) because it is excluded
Suite(test::src/test/codegen) not skipped for "bootstrap::test::Codegen" -- not in [src/test/ui, src/test/mir-opt/, src/test/debuginfo, src/test/ui-fulldeps]

Skipping Suite(test::src/test/debuginfo) because it is excluded
Skipping Suite(test::src/test/ui-fulldeps) because it is excluded
... about 100 more lines ...
```

After:
```

Skipping Suite(test::src/test/debuginfo) because it is excluded

Tells that `||` operators are not currently supported instead of not allowed. See https://github.com/rust-lang/rust/issues/53667#issuecomment-1066075876

In other words, this PR is pretty much trivial.

Rollup merge of #95301 - nnethercote:rm-NtTT, r=petrochenkov
Remove `Nonterminal::NtTT`.

It's only needed for macro expansion, not as a general element in the
AST. This commit removes it, adds `NtOrTt` for the parser and macro
expansion cases, and renames the variants in `NamedMatch` to better
match the new type.

rustdoc: add 🔒 to items with restricted visibility

This change marks items with restricted visibility with 🔒 when building with `--document-private-items`:

<img width="278" alt="Screen Shot 2022-03-20 at 23 50 24" src="https://user-images.githubusercontent.com/509209/159189513-9e4b09bb-6785-41a5-bfe2-df02f83f8641.png">

There also appears a “Restricted Visibility” tooltip when hovering over the emoji.

---

The original PR for reference:

This change makes private items slightly transparent (similar to `unstable` items in rustc):

<img width="272" alt="Screen Shot 2022-03-16 at 22 17 43" src="https://user-images.githubusercontent.com/509209/158692627-a1f6f5ec-e043-4aa2-9352-8d2b15c31c08.png">

I found myself using `--document-private-items` a lot recently because I find the documentation of private internals quite helpful when working on a larger project. However, not being able to distinguish private from public items (see #87785) when looking at the documentation makes this somewhat cumbersome.

This PR addresses the third suggestion of issue #87785 by marking private items typographically. It seems to me that the other suggestions are more involved but this is at least a first step.

A private item is also made slightly transparent in the path displayed in the header of a page:

<img width="467" alt="Screen Shot 2022-03-16 at 22 19 51" src="https://user-images.githubusercontent.com/509209/158692885-0bbd3417-3c0b-486f-b8ab-99c05c6fa7ca.png">

I am looking forward to feedback and suggestions.

0e4524e5b4 Auto merge of #94789 - compiler-errors:fatal-never, r=eddyb
Make fatal DiagnosticBuilder yield `!`

Fatal errors should really be fatal, so emitting them should cause us to exit at the same time.

Fine with just throwing away these changes if they're not worthwhile. Also, maybe we want to use an uninhabited enum instead of `!`.

r? `@eddyb` who has been working on `DiagnosticBuilder` stuff, feel free to reassign.

Rollup merge of #95016 - janpaul123:patch-1, r=dtolnay
Docs: make Vec::from_raw_parts documentation less strict

This is my first PR; be gentle!

In https://users.rust-lang.org/t/why-does-vec-from-raw-parts-require-same-size-and-not-same-size-capacity/73036/2?u=janpaul123 it was suggested to me that I should make a PR to make the documentation of `Vec::from_raw_parts` less strict, since we don't require `T` to have the same size, just `size_of::<T>() * capacity` to be the same, since that is what results in `Layout::size` being the same in `dealloc`, which is really what matters.

Also in https://users.rust-lang.org/t/why-does-vec-from-raw-parts-require-same-size-and-not-same-size-capacity/73036/8?u=janpaul123 it was suggested that it's better to use `slice::from_raw_parts`, which I think is useful advise that could also be mentioned in the docs, so I added that too.

Let me know what you think! :)

Rollup merge of #93755 - ChayimFriedman2:allow-comparing-vecs-with-different-allocators, r=dtolnay
Allow comparing `Vec`s with different allocators using `==`

See https://stackoverflow.com/q/71021633/7884305.

I did not changed the `PartialOrd` impl too because it was not generic already (didn't support `Vec<T> <=> Vec<U> where T: PartialOrd<U>`).

Does it needs tests?

I don't think this will hurt type inference much because the default allocator is usually not inferred (`new()` specifies it directly, and even with other allocators, you pass the allocator to `new_in()` so the compiler usually knows the type).

I think this requires FCP since the impls are already stable.
