so that it is the only pass responsible for elaboration, instead of
splitting this responsibility between the `StateTransform` and
`ElaborateBoxDerefs`.
Check projection types before inlining MIR
Fixes https://github.com/rust-lang/rust/issues/100550
I'm very unhappy with this solution, having to duplicate MIR validation code, but at least it removes the ICE.

A resume place is evaluated and assigned to only after a yield
terminator resumes. Ensure that locals used when evaluating the
resume place are live across the yield.
Elide superfluous storage markers
Follow the existing strategy of omitting the storage markers for temporaries
introduced for internal usage when elaborating derefs and deref projections.
Those temporaries are simple scalars which are used immediately after being
defined and never have their address taken. There is no benefit from storage
markers from either liveness analysis or code generation perspective.
Sync rustc_codegen_cranelift
The main highlights this time are support for parallel compilation of codegen units (by me) and improved windows support (by ``@afonso360)`` In addition ``@afonso360`` added abi-checker to cg_clif's CI. This has already catched an abi compatibility issue with AArch64. The fix has landed on Cranelift's main branch, but doesn't yet have a release. ``@uweigand`` also submitted a couple of PR's that will are prerequisites for supporting IBM's s390x architecture.

rustdoc: ayu code color selector more specific
According to https://github.com/rust-lang/rust/pull/100960#issuecomment-1225970579, this selector is only really intended to apply to item info. However, it's so broad that it's hard to tell when it deliberately applies vs where it accidentally applies.
let-else: break out to one scope higher for let-else
```@est31``` This PR follows up with #99518 which is to break out to the last remainder scope. It breaks to the out-most `region_scope` of the block if the first statement is a `let-else`.

Add a missing test case for impl generic mismatch
This suggestion use different span depending on whether the method has generics or not, so I added a test case about the method with some generics.
rustdoc: remove unused CSS rule
According to [blame], this rule was added to support enum struct variants. However, enum struct variants don't use tables in their design any more, so this rule does nothing.
[blame]: 87991d5f5d/src/librustdoc/html/static/css/rustdoc.css (L748)
Use `--userns=keep-id` when "docker" is really podman
Rootless podman creates a separate user namespace, where an inner
`LOCAL_USER_ID` will map to a different subuid range on the host.
The "keep-id" mode maps the current UID directly into the container.
This makes `src/ci/docker/run.sh` work better for testing container
images on systems running podman, where "docker" is just a shim.
Rewrite error index generator to greatly reduce the size of the pages
Fixes https://github.com/rust-lang/rust/issues/100736.
Instead of having all error codes in a same page (making the DOM way too big), I split the output into multiple files and generated a list of links (if there is an explanation) to the error codes' explanation into the already existing file.
I also used this opportunity to greatly simplify the code. Instead of needing a `build.rs`, I simply imported the file we want and wrote the macro which generates a function containing everything we need. We just need to call it to get the error codes and their explanation (if any). Also, considering the implementations between markdown and HTML formats differed even further, the `Formatter` trait was becoming too problematic so I removed it too.
You can test it [here](https://rustdoc.crud.net/imperio/rewrite-error-index/error-index.html).

Use par_body_owners for liveness
I did this refactoring while working on something else. Liveness is about bodies, there is no reason to use par_for_each_module here.
Tests are updated because things are visited in a different order. I checked diagnostics are same, just in a different (and IMO, better) order.
Suggest alternatives when trying to mutate a `HashMap`/`BTreeMap` via indexing
The error can be quite confusing to newcomers.
Fixes#100873.
I'm not so sure about the message, open to wording suggestions.
Coherence negative impls implied bounds
Fixes#93875
This PR is rebased on top of #100789 and it would need to include that one which is already r+ed.

Extra documentation for new formatting feature
Documentation of this feature was added in #90473 and released in Rust 1.58. However, high traffic macros did not receive new examples. Namely `println!()` and `format!()`.
The doc comments included in Rust are super important to the community- especially newcomers. I have met several other newbies like myself who are unaware of this recent (well about 7 months old now) update to the language allowing for convenient intra-string identifiers.
Bringing small examples of this feature to the doc comments of `println!()` and `format!()` would be helpful to everyone learning the language.

Closes https://github.com/rust-lang/rust/issues/100648
This PR will fix a suggestion error by taking into consideration also the `:?` symbol and act in a different way

N.B: I did not find a full way to test the change, any idea?
