Bump cc version in bootstrap
Among other changes, the newer cc release pulls in this fix:
b2792e33ff
This fixes errors when building compiler_builtins for UEFI targets.
Add test for raw-dylib with an external variable
All existing tests of link kind `raw-dylib` only validate the ability to link against functions, but it is also possible to link against variables.
This adds tests for linking against a variable using `raw-dylib` both by-name and by-ordinal.
Avoid invalidating the CFG in `MirPatch`
As a part of this change, we adjust `MirPatch` to not needlessly create unnecessary resume blocks.
r? `@tmiasko`
Always create elided lifetimes, even if inferred.
`PathSource` gives the context in which a path is encountered. The same `PathSource` is used for the full path and the `QSelf` part.
Therefore, we can only rely on `PathSource` to know whether typechecking will be able to infer the lifetimes, not whether we need to insert them at all.

Some `is_useful` cleanups
#98582 was reverted because it was a perf regression.
https://github.com/rust-lang/rust/pull/99806 reintroduces the changes, but this PR picks individual ones that have no regressions.

Add back Send and Sync impls on ChunksMut iterators
Fixes https://github.com/rust-lang/rust/issues/100014
These were accidentally removed in #94247 because the representation was changed from `&mut [T]` to `*mut T`, which has `!Send + !Sync`.

Add tests for raw-dylib with vectorcall, and fix vectorcall code generation
* Adds tests for using `raw-dylib` (#58713) with `vectorcall`.
* Fixed code generation for `vectorcall` (parameters have to be marked with `InReg`, just like `fastcall`).
* Enabled running the `raw-dylib` `fastcall` tests when using MSVC (since I had to add support in the test for running MSVC-only tests since GCC doesn't support `vectorcall`).
internal: Update `xtask promote` and release instructions
Update `xtask` for the subtree workflow. This doesn't explain how to do a `rust -> RA` sync, since that's definitely more involved, but will probably only happen rarely.
Remove `TreeAndSpacing`.
A `TokenStream` contains a `Lrc<Vec<(TokenTree, Spacing)>>`. But this is
not quite right. `Spacing` makes sense for `TokenTree::Token`, but does
not make sense for `TokenTree::Delimited`, because a
`TokenTree::Delimited` cannot be joined with another `TokenTree`.
This commit fixes this problem, by adding `Spacing` to `TokenTree::Token`,
changing `TokenStream` to contain a `Lrc<Vec<TokenTree>>`, and removing the
`TreeAndSpacing` typedef.
The commit removes these two impls:
- `impl From<TokenTree> for TokenStream`
- `impl From<TokenTree> for TreeAndSpacing`
These were useful, but also resulted in code with many `.into()` calls
that was hard to read, particularly for anyone not highly familiar with
the relevant types. This commit makes some other changes to compensate:
- `TokenTree::token()` becomes `TokenTree::token_{alone,joint}()`.
- `TokenStream::token_{alone,joint}()` are added.
- `TokenStream::delimited` is added.
This results in things like this:
```rust
TokenTree::token(token::Semi, stmt.span).into()
```
changing to this:
```rust
TokenStream::token_alone(token::Semi, stmt.span)
```
This makes the type of the result, and its spacing, clearer.
These changes also simplifies `Cursor` and `CursorRef`, because they no longer
need to distinguish between `next` and `next_with_spacing`.
r? `@petrochenkov`
use `check_region_obligations_and_report_errors` to avoid ICEs
If we don't call `process_registered_region_obligations` before `resolve_regions_and_report_errors` then we'll ICE if we have any region obligations, and `check_region_obligations_and_report_errors` just does both of these for us in a nice convenient function.
Fixes#53475

Generate correct suggestion with named arguments used positionally
Address issue #99265 by checking each positionally used argument
to see if the argument is named and adding a lint to use the name
instead. This way, when named arguments are used positionally in a
different order than their argument order, the suggested lint is
correct.
For example:
```
println!("{b} {}", a=1, b=2);
```
This will now generate the suggestion:
```
println!("{b} {a}", a=1, b=2);
```
Additionally, this check now also correctly replaces or inserts
only where the positional argument is (or would be if implicit).
Also, width and precision are replaced with their argument names
when they exists.
Since the issues were so closely related, this fix for issue #99265
also fixes issue #99266.

LLVM 15 compatibility fixes
These are LLVM 15 compatibility fixes split out from #99464. There are three changes here:
* Emit elementtype attribtue for ldrex/strex intrinsics. This is requires as part of the opaque pointers migration.
* Make more tests compatible with opaque pointers. These are either new or aren't run on x86.
* Remove a test for `#[rustc_allocator]`. Since #99574 there are more requirement on the function signature. I dropped the test entirely, since we already test the effect of the attribute elsewhere.
* The main change: When a worker thread emits an error, wait for other threads to finish before unwinding the main thread and exiting. Otherwise workers may end up using globals for which destructors have already been run. This was probably never quite correct, but became an active problem with LLVM 15, because it started using global dtors in critical places, as part of ManagedStatic removal.
Fixes#99432 (and probably also #95679).

internal: Be more explicit when filtering built-in completions
We return every built-in type here, but only have `u32` in the tests, so let's look for that one to make tests more reliable across platforms.
Use line numbers relative to the function in mir-opt tests
As shown in #99770, the line numbers can be a big source of needless and confusing diffs. This PR adds a new flag `-Zmir-pretty-relative-line-numbers` to make them relative to the function declaration, which avoids most needless diffs from attribute changes.
`@JakobDegen` told me that there has been a zulip conversation about disabling line numbers with mixed opinions, so I'd like to get some feedback here, for this hopefully better solution.
r? rust-lang/wg-mir-opt
fix: Do completions in path qualifier position
Fixes https://github.com/rust-lang/rust-analyzer/issues/12566
Not too happy with the duplication needed for this, but it is what it is. Completions in path qualifiers will have to be filtered properly still, but its better to show too many completions for this than too few for now.
Sync `rust-analyzer`, add `rust-analyzer-proc-macro-srv` binary to Rustc component
As discussed earlier with `@jyn514` and `@pietroalbini,` I'm also going to use this PR to have `dist::Rustc` build the `rust-analyzer-proc-macro-srv` binary introduced in:
* https://github.com/rust-lang/rust-analyzer/pull/12871
