If it's a static candidate, then it's already implemented. Do not suggest
it a second time for implementing.

This reverts commit a6b5f95.

We really shouldn't be overriding this kind of stuff unless the browser
default is really broken (like outlining the thing that isn't clickable).
This directly reverts b8f4e74.

Add tests for static async functions in traits

This patch adds test cases for AFIT, the majority of which are currently expected to run as `check-fail`.

---

Note: I grabbed the cases from https://hackmd.io/SwRcXCiWQV-WRJ4BYs53fA

Also, I'm not sure if the `async-associated-types2` and `async-associated-types2-desugared` are correct, I modified them a bit from the examples in the HackMD.

Add suggestions for unsafe impl error codes

Adds suggestions for users to add `unsafe` to trait impls that should be `unsafe`, and remove `unsafe` from trait impls that do not require `unsafe`

With the folllowing code:

```rust
struct Foo {}

struct Bar {}

trait Safe {}

unsafe trait Unsafe {}

impl Safe for Foo {} // ok

impl Unsafe for Foo {} // E0200

unsafe impl Safe for Bar {} // E0199

unsafe impl Unsafe for Bar {} // ok

// omitted empty main fn
```

The current rustc output is:
```
error[E0199]: implementing the trait `Safe` is not unsafe
  --> e0200.rs:13:1
   |
13 | unsafe impl Safe for Bar {} // E0199
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^

error[E0200]: the trait `Unsafe` requires an `unsafe impl` declaration
  --> e0200.rs:11:1
   |
11 | impl Unsafe for Foo {} // E0200
   | ^^^^^^^^^^^^^^^^^^^^^^

error: aborting due to 2 previous errors

Some errors have detailed explanations: E0199, E0200.
For more information about an error, try `rustc --explain E0199`.
```

With this PR, the future rustc output would be:
```
error[E0199]: implementing the trait `Safe` is not unsafe
  --> ../../temp/e0200.rs:13:1
   |
13 | unsafe impl Safe for Bar {} // E0199
   | ^^^^^^^^^^^^^^^^^^^^^^^^^^^
   |
help: remove `unsafe` from this trait implementation
   |
13 - unsafe impl Safe for Bar {} // E0199
13 + impl Safe for Bar {} // E0199
   |

error[E0200]: the trait `Unsafe` requires an `unsafe impl` declaration
  --> ../../temp/e0200.rs:11:1
   |
11 | impl Unsafe for Foo {} // E0200
   | ^^^^^^^^^^^^^^^^^^^^^^
   |
   = note: the trait `Unsafe` enforces invariants that the compiler can't check. Review the trait documentation and make sure this implementation upholds those invariants before adding the `unsafe` keyword

Fix unwanted merge of inline doc comments for impl blocks

Fixes rust-lang#102909.

We need this merge mechanism for inlined items but it's completely unwanted for impl blocks (at least the doc comments are, not the other attributes) since we want to keep what `cfg()` is put on the `pub use` or other attributes.

diagnostics: do not suggest static candidates as traits to import

If it's a static candidate, then it's already implemented. Do not suggest it a second time for implementing.

Partial fix for rust-lang#102354

Migrate source line numbers CSS to CSS variables

Part of rust-lang#98460.

No UI changes.

Remap early bound lifetimes in return-position `impl Trait` in traits too

Fixes part of rust-lang#103457

r? `@cjgillot,` though feel free to reassign, just thought you'd have sufficient context to review.

…piler-errors

Emit a nicer error on `impl Self {`

currently it emits a "cycle detected error" but this PR makes it emit a more user friendly error specifically saying that `Self` is disallowed in that position. this is a pretty hacky fix so i dont expect this to be merged (I basically only made this PR because i wanted to see if CI passes)

Don't carry MIR location in `ConstraintCategory::CallArgument`

It turns out that `ConstraintCategory::CallArgument` cannot just carry a MIR location in it, since we may bubble them up to totally different MIR bodies.

So instead, revert the commit a6b5f95, and instead just erase regions from the original `Option<Ty<'tcx>>` that it carried, so that it doesn't ICE with the changes in rust-lang#103220.

Best reviewed in parts -- the first is just a revert, and the second is where the meaningful changes happen.

Fixes rust-lang#103624
