Rollup merge of #92402 - pr2502:while-let-typo, r=oli-obk
Suggest while let x = y when encountering while x = y

Extends #75931 to also detect where the `let` might be missing from `while let` expressions.

Rollup merge of #92237 - compiler-errors:issue-92100, r=cjgillot
Visit expressions in-order when resolving pattern bindings

[edited:] Visit the pattern's sub-expressions before defining any bindings.

Otherwise, we might get into a case where a Lit/Range expression in a pattern has a qpath pointing to a Ident pattern that is defined after it, causing an ICE when lowering to HIR. I have a more detailed explanation in the issue linked.

Fixes #92100

Tighten span when suggesting lifetime on path

This is kind of a hack.

Really the issue here is that we want to suggest the segment's span if the path resolves to something defined outside of the macro, and the macro's span if it resolves to something defined within.. I'll look into seeing if we can do something like that.

Fixes #92324

This was originally proposed in https://github.com/rust-lang/rust/pull/74554#discussion_r466203544. As well as removing the icky `SymbolStr` type, it allows the removal of a lot of `&` and `*` occurrences.

Include rustc version in `rustc_span::StableCrateId`

`rustc_span::def_id::StableCrateId` is a hash of various data about a crate during compilation. This PR includes the version of `rustc` in the input when computing this hash. From a cursory reading of [RFC 2603](https://rust-lang.github.io/rfcs/2603-rust-symbol-name-mangling-v0.html), this appears to be acceptable within that design.

In order to pass the `mir-opt` and `ui` test suites, this adds new [normalization for hashes and symbol names in `compiletest`](https://github.com/rust-lang/rust/pull/89836/files#diff-03a0567fa80ca04ed5a55f9ac5c711b4f84659be2d0ac4a984196d581c04f76b). These are enabled by default, but we might prefer it to be configurable.

In the UI tests, I had to truncate a significant amount of error annotations in v0 symbols (and maybe some legacy) in order to get the normalization to work correctly. (See https://github.com/rust-lang/rust/issues/90116.)

Closes #85142.

8cddcd39ba Remove SymbolStr.
By changing `as_str()` to take `&self` instead of `self`, we can just
return `&str`. We're still lying about lifetimes, but it's a smaller lie
than before, where `SymbolStr` contained a (fake) `&'static str`!

Issue 90702 fix: Stop treating some crate loading failures as fatal errors

Surface mulitple `extern crate` resolution errors at a time.

This is achieved by creating a dummy crate, instead of aborting directly after the resolution error. The `ExternCrateError` has been added to allow propagating the resolution error from `rustc_metadata` crate to the `rustc_resolve` with a minimal public surface. The `import_extern_crate` function is a block that was factored out from `build_reduced_graph_for_item` for better organization. The only added functionality made to it where the added error handling in the `process_extern_crate` call. The remaining bits in this function are the same as before.

Resolves #90702

Lint elided lifetimes in path during lifetime resolution.

The lifetime elision lint is known to be brittle and can be redundant with later lifetime resolution errors. This PR aims to remove the redundancy by performing the lint after lifetime resolution.

This PR proposes to carry the information that an elision should be linted against by using a special `LifetimeName`. I am not certain this is the best solution, but it is certainly the easiest.

expand: Turn `ast::Crate` into a first class expansion target

And stop creating a fake `mod` item for the crate root when expanding a crate, thus addressing FIXMEs left in https://github.com/rust-lang/rust/pull/82238, and making a step towards a proper support for crate-level macro attributes (cc #54726).

I haven't added token collection support for the whole crate in this PR, maybe later.

Do not visit attributes in `ItemLowerer`.

By default, AST visitors visit expressions that appear in key-value attributes.
Those expressions should not be lowered to HIR, as they do not correspond to actually compiled code.

Since an attribute cannot produce meaningful HIR, just skip them altogether.
