Corrects the float_equality_without_abs lint

Fixes an issue in the `float_equality_without_abs` lint. The lint suggestion was configured in a way that it lints the whole error and not just the subtraction part. In the current configuration the lint would suggest to change the expression in a wrong way, e.g.
```rust
let _ = (a - b) < f32::EPSILON; // before
let _ = (a - b).abs(); // after
```
This was dicovered by @flip1995. (See discussion of PR #5952).

Also the suggestion is now formatted via `utils::sugg`.

dd07860b83 Auto merge of #5941 - ThibsG:InlineInCopyPassByRef, r=yaahc 
Don't lint if it has always inline attribute

Don't trigger the lint `trivially_copy_pass_by_ref` if it has `#[inline(always)]` attribute.

Note: I am not particularly familiar with `inline` impacts, so I implemented this the way that if only `#[inline]` attribute is here (without `always`), the lint will still trigger. Also, it will still trigger if it has `#[inline(never)]`.
Just tell me if it sounds too much conservative.

5b07b9ed61 Widen understanding of prelude import 
Prelude imports are exempt from wildcard import warnings. Until now only
imports of the form

```
use ...::prelude::*;

were considered. This change makes it so that the segment `prelude` can
show up anywhere, for instance:

```
use ...::prelude::v1::*;

9e73d33680 Rollup merge of #75098 - Ryan1729:clippy-pointer-cast-lint-experiment, r=oli-obk 
Clippy pointer cast lint experiment

This PR is an experiment about exposing more parts of `rustc_typeck` for use in `clippy`. In particular, the code that checks where a cast is valid or not was exposed, which necessitated exposing [`FnCtxt`](https://doc.rust-lang.org/nightly/nightly-rustc/rustc_typeck/check/struct.FnCtxt.html), and figuring out how to create an instance of that type inside `clippy`.

This was prompted by [this clippy issue](https://github.com/rust-lang/rust-clippy/issues/2064).

Fix ICE in `loops` module

changelog: Fix ICE related to `needless_collect` when a call to `iter()` was not present.

I went for restoring the old suggestion of `next().is_some()` over `get(0).is_some()` given that `iter()` is not necessarily present (could be e.g. `into_iter()` or `iter_mut()`)  and that the old suggestion could change semantics, e.g. a call to `filter()` could be present between `iter()` and the collect part.

01bba2c532 Eliminate the SessionGlobals from librustc_ast. 
By moving `{known,used}_attrs` from `SessionGlobals` to `Session`. This
means they are accessed via the `Session`, rather than via TLS. A few
`Attr` methods and `librustc_ast` functions are now methods of
`Session`.

All of this required passing a `Session` to lots of functions that didn't
already have one. Some of these functions also had arguments removed, because
those arguments could be accessed directly via the `Session` argument.

`contains_feature_attr()` was dead, and is removed.

Some functions were moved from `librustc_ast` elsewhere because they now need
to access `Session`, which isn't available in that crate.
- `entry_point_type()` --> `librustc_builtin_macros`
- `global_allocator_spans()` --> `librustc_metadata`
- `is_proc_macro_attr()` --> `Session`
