Rollup merge of #5874 - camelid:patch-1, r=flip1995
Make the docs clearer for new contributors

It confused me before, so I made it extra obvious that you need to run
a script to set up your toolchain before you can build Clippy.

I also added a note so that new contributors aren't confused when
Clippy doesn't build as a result of a change in rustc's internals.

changelog: make `CONTRIBUTING.md` clearer for new contributors

Rollup merge of #5870 - ebroto:5789_allow_unsafe_derive_deserialize, r=flip1995
enable #[allow(clippy::unsafe_derive_deserialize)]

Before this change this lint could not be allowed as the code we are checking is automatically generated.

changelog: Enable using the `allow` attribute on top of an ADT linted by [`unsafe_derive_deserialize`].

Fixes: #5789

7228368953 Auto merge of #5882 - dima74:ra_setup-prevent-compile-rustc, r=Manishearth
Prevent compile parts of rustc when using `cargo dev ra-setup`

Currently after running `cargo dev ra-setup` the following lines are added to `Cargo.toml`:

```toml
[target]
rustc_data_structures = { path = ".../rust/src/librustc_data_structures" }
rustc_driver = { path = ".../rust/src/librustc_driver" }
rustc_errors = { path = ".../rust/src/librustc_errors" }
rustc_interface = { path = ".../rust/src/librustc_interface" }
rustc_middle = { path = ".../rust/src/librustc_middle" }
```

This pull request adds dependencies for `rustc` crates under `cfg(NOT_A_PLATFORM)`, thus preventing them from compiling together with clippy:

```toml
[target.'cfg(NOT_A_PLATFORM)'.dependencies]
rustc_data_structures = { path = ".../rust/src/librustc_data_structures" }
rustc_driver = { path = ".../rust/src/librustc_driver" }
rustc_errors = { path = ".../rust/src/librustc_errors" }
rustc_interface = { path = ".../rust/src/librustc_interface" }
rustc_middle = { path = ".../rust/src/librustc_middle" }
```

---

This approach was [originally proposed for IntelliJ Rust](https://github.com/intellij-rust/intellij-rust/issues/1618#issuecomment-459098749), and looks like it works for rust-analyzer too.

70c46de012 Auto merge of #5877 - ebroto:5872_loops_ice, r=Manishearth
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.

Fixes #5872

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`

a7fa264ae7 Auto merge of #74821 - oli-obk:const_eval_read_uninit_fast_path, r=wesleywiser
Check whether locals are too large instead of whether accesses into them are too large

Essentially this stops const prop from attempting to optimize

```rust
let mut x = [0_u8; 5000];
x[42] = 3;
```

I don't expect this to be a perf improvement without #73656 (which is also where the lack of this PR will be a perf regression).
