This ensures we get still get lints for generic contexts.

- Change to warnings so that all lints are emitted
- Expect build-pass
- Change placeholder FIXME to WARN.

Add missing comma

Added missing comma in doc comment

update `FnCtxt::lookup_method` docs

Looks like the doc comment was forgotten during a refactor.

Fix broken link in documentation for String::from_utf8

Clean up E0517 explanation

r? @Dylan-DPC

Remove the last remnant of unsigned Neg

It's been gone since #23945, before Rust 1.0. The former wrapping
semantics have also been available as inherent methods for a long time
now. There's no reason to keep this unused macro around.

Update LLVM submodule fixing sanitizers build with glibc 2.31

Fixes #69556.

Improve async-await/generator obligation errors in some cases

Fixes #68112.

This change is best read one commit at a time (I add a test at the beginning and update it in each change after).

The `test2` function is a case I found while writing the test that we don't handle with this code yet. I don't attempt to fix it in this PR, but it's a good candidate for future work.

Rename AssocKind::Method to AssocKind::Fn

Part of https://github.com/rust-lang/rust/issues/60163.

I personally find this clearer.

allow const generics in const fn

This was explicitly forbidden before. As we were unable to think of a reason
why this should still be the case, this check has been removed.
