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).

To compile rustc with profiling information, `compiler-rt` from
LLVM is required. Building it requires the `src/llvm-project` submodule
to be initialized and updated.
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.
Prior to this fix, `-Z location-detail` provided no mechanism for
disabling all location details. This commit also adds a test case
to verify that this option continues to work as intended, and
clarifies the documentation of this option.
fix: remove fake no_dead_strip for osx
Closes https://github.com/rust-lang/rust/issues/99788
Link arg `-no_dead_strip` doesn't exist on OSX at all.
The `no_gc_sections` function was never called before export-executable-symols implementation, and `export-executable-symbols` still works, so we just remove it.

Fix PermissionDenied UI tests on WSL
On my WSL with `appendWindowsPath=true`, running an invalid command returns `PermissionDenied` instead of `NotFound`, causing two UI tests to fail.
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.

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.
