Remove mention of possibility to specify the MSRV with a tilde/caret

As `@taiki-e` explained in https://github.com/rust-lang/rust-clippy/pull/6379#discussion_r530743279, mentioning this might be problematic.

f303168a0d Auto merge of #77671 - flip1995:lint_list_always_plugins, r=oli-obk,Manishearth
Always print lints from plugins, if they're available

Currently you can get a list of lints and lint groups by running `rustc
-Whelp`. This prints an additional line at the end:
```
Compiler plugins can provide additional lints and lint groups. To see a listing of these, re-run `rustc -W help` with a crate filename.
```

Clippy is such a "compiler plugin", that provides additional lints.
Running `clippy-driver -Whelp` (`rustc` wrapper) still only prints the
rustc lints with the above message at the end. But when running
`clippy-driver -Whelp main.rs`, where `main.rs` is any rust file, it
also prints Clippy lints. I don't think this is a good approach from a
UX perspective: Why is a random file necessary to print a help message?

This PR changes this behavior: Whenever a compiler callback
registers lints, it is assumed that these lints come from a plugin and
are printed without having to specify a Rust source file.

Fixes rust-lang/rust-clippy#6122

cc `@Manishearth` `@ebroto` for the Clippy changes.

f6827839c0 Move lev_distance to rustc_ast, make non-generic
rustc_ast currently has a few dependencies on rustc_lexer. Ideally, an AST
would not have any dependency its lexer, for minimizing unnecessarily
design-time dependencies. Breaking this dependency would also have practical
benefits, since modifying rustc_lexer would not trigger a rebuild of rustc_ast.

This commit does not remove the rustc_ast --> rustc_lexer dependency,
but it does remove one of the sources of this dependency, which is the
code that handles fuzzy matching between symbol names for making suggestions
in diagnostics. Since that code depends only on Symbol, it is easy to move
it to rustc_span. It might even be best to move it to a separate crate,
since other tools such as Cargo use the same algorithm, and have simply
contain a duplicate of the code.

This changes the signature of find_best_match_for_name so that it is no
longer generic over its input. I checked the optimized binaries, and this
function was duplicated at nearly every call site, because most call sites
used short-lived iterator chains, generic over Map and such. But there's
no good reason for a function like this to be generic, since all it does
is immediately convert the generic input (the Iterator impl) to a concrete
Vec<Symbol>. This has all of the costs of generics (duplicated method bodies)
with no benefit.

Changing find_best_match_for_name to be non-generic removed about 10KB of
code from the optimized binary. I know it's a drop in the bucket, but we have
to start reducing binary size, and beginning to tame over-use of generics
is part of that.

f897d27d8b Auto merge of #6339 - CDirkx:redundant-pattern-match-poll, r=ebroto
Change `redundant_pattern_matching` to also lint `std::task::Poll`

`reduntant_pattern_matching` currently lints pattern matching on `Option` and `Result` where the `is_variant` utility methods could be used instead: `is_some`, `is_none`, `is_ok`, `is_err`. This PR extends this behaviour to `std::task::Poll`, suggesting the methods `is_pending` and `is_ready`.

Motivation: The current description of `redundant_pattern_matching` mentions

> It's more concise and clear to just use the proper utility function

which in my mind applies to `Poll` as well.

Qualify `panic!` as `core::panic!` in non-built-in `core` macros

Fixes #78333.

-----

Otherwise code like this

    #![no_implicit_prelude]

    fn main() {
        ::std::todo!();
        ::std::unimplemented!();
    }

will fail to compile, which is unfortunate and presumably unintended.

This changes many invocations of `panic!` in a `macro_rules!` definition
to invocations of `$crate::panic!`, which makes the invocations hygienic.

Note that this does not make the built-in macro `assert!` hygienic.

Drop support for all cloudabi targets

`cloudabi` is a tier-3 target, and [it is no longer being maintained upstream][no].

This PR drops supports for cloudabi targets. Those targets are:
* aarch64-unknown-cloudabi
* armv7-unknown-cloudabi
* i686-unknown-cloudabi
* x86_64-unknown-cloudabi

Since this drops supports for a target, I'd like somebody to tag `relnotes` label to this PR.

Some other issues:
* The tidy exception for `cloudabi` crate is still remained because
  * `parking_lot v0.9.0` and `parking_lot v0.10.2` depends on `cloudabi v0.0.3`.
  * `parking_lot v0.11.0` depends on `cloudabi v0.1.0`.

Small grammar, punctuation, and code style improvements to docs

changelog: Made small grammar, punctuation, and code style improvements to docs

I recently found some places in rust-lang/rust that had lists without spaces after commas, which led me to look for more places, which led me over here to find:

- Some similar lists in code examples that could use spaces after commas to be idiomatic Rust style
- Some lists in documentation text that didn't have spaces after commas, needed an Oxford comma (fight me), or were otherwise misformatted
- Some other grammar improvements in the area of the other changes

These changes should only be in user-facing documentation or output.
