This option prints all supported values for -Csplit-debuginfo=.., i.e.
only stable ones on stable/beta and all of them on nightly/dev.

fix: lint against the functions `LintContext::{lookup_with_diagnostics,lookup,struct_span_lint,lint}`, `TyCtxt::struct_lint_node`, `LintLevelsBuilder::struct_lint`.

Place config.toml in current working directory if config not found

Fixes an issue where bootsrapping a Rust build would place `config.toml` in `{src_root}` rather than the current working directory

disable btree size tests on Miri

Seems fine not to run these in Miri, they can't have UB anyway. And this lets us do layout randomization in Miri.

run alloc benchmarks in Miri and fix UB

Miri since recently has a "fake monotonic clock" that works even with isolation. Its measurements are not very meaningful but it means we can run these benches and check them for UB.

And that's a good thing since there was UB here: fixes rust-lang#104096.

Add split-debuginfo print option

This option prints all supported values for `-Csplit-debuginfo=..`, i.e. only stable ones on stable/beta and all of them on nightly/dev.

Motivated by 1.65.0 regression causing builds with the following entry in `Cargo.toml` to fail on Windows:
```toml
[profile.dev]
split-debuginfo = "unpacked"
```

See rust-lang/cargo#11347 for details.

This will lead to closing rust-lang#103976.

rustdoc: Add mutable to the description

`mutable` is missing from the description.  Currently the description for [align_to](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L3498) is the same as [align_to_mut](https://github.com/rust-lang/rust/blob/master/library/core/src/slice/mod.rs#L3559)

Fix `const_fn_trait_ref_impl`, add test for it

Fix invalid background-image file name

This is a follow-up of rust-lang#101702.

Apparently the image hash was the wrong one. You can see the error in https://doc.rust-lang.org/nightly/core/primitive.u16.html?search=hello too.

I really need to check if I can adds check for resources load errors in `browser-ui-test`.

Clarify licensing situation of MPSC and SPSC queue

Originally, these two files were licensed under the `BSD-2-Clause` license, as they were based off sample code on a blog licensing those snippets under that license:

* `library/std/src/sync/mpsc/mpsc_queue.rs`
* `library/std/src/sync/mpsc/spsc_queue.rs`

In 2017 though, the author of that blog agreed to relicense their code under the standard `MIT OR Apache-2.0` license in rust-lang#42149. This PR clarifies the situation in the files by expanding the comment at the top of the file.

Remove an address comparison from the parser

Originally this check was added in rust-lang#68985, as suggested by rust-lang@940f657#r376850175. I don't think that this address check is a robust way of making parser more robust.

This code is also extensively tested by [`ui/parser/issues/issue-35813-postfix-after-cast.rs`](https://github.com/rust-lang/rust/blob/57d3c58ed6e0faf89a62411f96c000ffc9fd3937/src/test/ui/parser/issues/issue-35813-postfix-after-cast.rs).
