diagnostics: regression test for derive bounds
Closes #79076

Suggest wrapping patterns in enum variants
Structured suggestion to wrap a pattern in a single-field enum or struct:
```diff
struct A;
enum B {
A(A),
}
fn main(b: B) {
match b {
- A => {}
+ B::A(A) => {}
}
}
```
Half of #94942, the other half I'm not exactly sure how to fix.
Also includes two drive-by changes (that I am open to splitting out into another PR, but thought they could be rolled up into this one):
- 07776c111f07b887cd46b752870cd3fd76b2ba7c: Makes sure not to suggest wrapping if it doesn't have tuple field constructor (i.e. has named fields)
- 8f2bbb18fd53e5008bb488302dbd354577698ede: Also suggest wrapping expressions in a tuple struct (not just enum variants)

yaahc:termination-stabilization-celebration-station, r=joshtriplett
Stabilize Termination and ExitCode
From https://github.com/rust-lang/rust/issues/43301
This PR stabilizes the Termination trait and associated ExitCode type. It also adjusts the ExitCode feature flag to replace the placeholder flag with a more permanent name, as well as splitting off the `to_i32` method behind its own permanently unstable feature flag.
This PR stabilizes the termination trait with the following signature:
```rust
pub trait Termination {
fn report(self) -> ExitCode;
}
```
The existing impls of `Termination` are effectively already stable due to the prior stabilization of `?` in main.
This PR also stabilizes the following APIs on exit code
```rust
#[derive(Clone, Copy, Debug)]
pub struct ExitCode(_);
impl ExitCode {
pub const SUCCESS: ExitCode;
pub const FAILURE: ExitCode;
}
impl From<u8> for ExitCode { /* ... */ }
```
---
All of the previous blockers have been resolved. The main ones that were resolved recently are:
* The trait's name: We decided against changing this since none of the alternatives seemed particularly compelling. Instead we decided to end the bikeshedding and stick with the current name. ([link to the discussion](https://rust-lang.zulipchat.com/#narrow/stream/219381-t-libs/topic/Termination.2FExit.20Status.20Stabilization/near/269793887))
* Issues around platform specific representations: We resolved this issue by changing the return type of `report` from `i32` to the opaque type `ExitCode`. That way we can change the underlying representation without affecting the API, letting us offer full support for platform specific exit code APIs in the future.
* Custom exit codes: We resolved this by adding `From<u8> for ExitCode`. We choose to only support u8 initially because it is the least common denominator between the sets of exit codes supported by our current platforms. In the future we anticipate adding platform specific extension traits to ExitCode for constructors from larger or negative numbers, as needed.

Remove header field from clean::Function
Fixes https://github.com/rust-lang/rust/issues/89673.
This is another take on https://github.com/rust-lang/rust/issues/89673 (compared to https://github.com/rust-lang/rust/pull/91217) but very different on the approach: I moved the header call in one place but still require to have the `clean::Item` so I can use the `DefId` to get what is missing.

Add suggestion to borrow `Fn` and `FnMut` params/opaque/closures instead of move
I think that Closure/ParamTy/Opaque are all "opaque" enough that it's meaningful to suggest borrowing them instead of moving them at their usage sites when we see a move error. See the attached issue for example.
Is this suggestion too general? I could perhaps use the move site information to limit this to places like fn calls, but I don't know enough about mir borrowck to know if that's an easy change.
Fixes #90828

`needs_note` is false if we've already suggested why the type is Copy...
but that has nothing to do with the diagnostic.

bootstrap: better error message for no_std docs
Currently if one tries to build std documentation for a no_std target, you get a confusing error message:
`error: The argument '--package [<SPEC>...]' was provided more than once, but cannot be used multiple times`
This is because [`std_cargo`](https://github.com/rust-lang/rust/blob/600ec284838c52d1f6657c2cf0097b58970b133b/src/bootstrap/compile.rs#L299-L305) has a built-in `-p alloc` argument that conflicts with the `cargo rustdoc` command used in the Std doc step.
This just adds a better error message in this scenario. It may be possible to fix this correctly, but that would likely be a bit more of an invasive change that I don't have time for right now.

[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.

resolve: Simplify some diagnostic code to avoid an ICE
No need to resolve those paths, they are already resolved, we just need to take the results from `partial_res_map`.

Tell users that `||` operators are not currently supported in let chain expressions
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.

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.
