Rollup merge of #105769 - lyming2007:issue-105177-fix, r=eholk
add function to tell the identical errors for ambiguity_errors

if 2 errors of the kind and ident and span of the ident, b1, b2 and misc1 misc2 are the same we call these 2 ambiguity errors identical
prevent identical ambiguity error from pushing into vector of ambiguity_errors this will fix #105177

With this commit we start to make some simple

we generate some helper messages in case the

and suggest the correct rust method.

We already use a mix of `Literal` and `Lit`. The latter is better
because it is shorter without causing any ambiguity.

Prefer doc comments over `//`-comments in compiler

Doc comments are generally nicer: they show up in the documentation, they are shown in IDEs when you hover other mentions of items, etc. Thus it makes sense to use them instead of `//`-comments.

privacy: Fix more (potential) issues with effective visibilities

Continuation of https://github.com/rust-lang/rust/pull/103965.
See individual commits for more detailed description of the changes.

The shortcuts removed in 4eb63f618e and c7c7d16727 could actually be correct (or correct after some tweaks), but they used global reasoning like "we can skip this update because if the code compiles then some other update should do the same thing eventually".
I have some expertise in this area, but I still have doubt whether such global reasoning was correct or not, especially in presence of all possible exotic cases with imports.
After this PR all table changes should be "locally correct" after every update, even if it may be overcautious.
If similar optimizations are introduced again they will need detailed comments explaining why it's legal to do what they do and providing proofs.

Avoid `GenFuture` shim when compiling async constructs

Previously, async constructs would be lowered to "normal" generators, with an additional `from_generator` / `GenFuture` shim in between to convert from `Generator` to `Future`.

The compiler will now special-case these generators internally so that async constructs will *directly* implement `Future` without the need to go through the `from_generator` / `GenFuture` shim.

The primary motivation for this change was hiding this implementation detail in stack traces and debuginfo, but it can in theory also help the optimizer as there is less abstractions to see through.

---

Given this demo code:

```rust
pub async fn a(arg: u32) -> Backtrace {
    let bt = b().await;
    let _arg = arg;
    bt
}

pub async fn b() -> Backtrace {
    Backtrace::force_capture()
}
```

I would get the following with the latest stable compiler (on Windows):

```
   4: async_codegen:🅱️:async_fn$0
             at .\src\lib.rs:10
   5: core::future::from_generator::impl$1::poll<enum2$<async_codegen:🅱️:async_fn_env$0> >

   6: async_codegen:🅰️:async_fn$0

```

whereas now I get a much cleaner stack trace:

```
   3: async_codegen:🅱️:async_fn$0
             at .\src\lib.rs:10
   4: async_codegen:🅰️:async_fn$0

```

7e76d94a22 effective visibility: Always add table entries for nodes used as parents
Previously if the parent was not in the table, and there was nothing to inherit from, the child's private visibility was used, but that's not correct - the parent may have a larger visibility so we should set it to at least the parent's private visibility.
That parent's private visibility is also inserted into the table for caching, so it's not recalculated later if used again.

f0843b89d1 effective visibility: Remove questionable optimizations
First, they require eagerly calculating private visibility (current normal module), which is somewhat expensive.
Private visibilities are also lost once calculated, instead of being cached in the table.

Second, I cannot prove that the optimizations are correct.
Maybe they can be partially reinstated in the future in cases when it's cheap and provably correct to do them.
They will also probably be merged into `fn update` in that case.
