439bae62a4 Auto merge of #5884 - Ryan1729:patch-1, r=flip1995 
Add the other overloadable operations to suspicious_arithmetic_impl

In #2268 I idly mused that the other user-overloadable operations could be added to this lint. Knowing that the lint was arguably incomplete was gnawing at the back of my mind, so I figured that I might as well make this PR, particularly given the change needed was so small.

changelog: Start warning on suspicious implementations of the `BitAnd`, `BitOr`, `BitXor`, `Rem`, `Shl`, and `Shr` traits.

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).

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.

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`
