93dd620241 Auto merge of #114489 - compiler-errors:rpitit-capture-all, r=oli-obk 
Make RPITITs capture all in-scope lifetimes

Much like #114616, this implements the lang team decision from this T-lang meeting on [opaque captures strategy moving forward](https://hackmd.io/sFaSIMJOQcuwCdnUvCxtuQ?view). This will be RFC'd soon, but given that RPITITs are a nightly feature, this shouldn't necessarily be blocked on that.

We unconditionally capture all lifetimes in RPITITs -- impl is not as simple as #114616, since we still need to duplicate RPIT lifetimes to make sure we reify any late-bound lifetimes in scope.

Closes #112194

Rollup merge of #115311 - dtolnay:usearcself, r=compiler-errors 
Revert "Suggest using `Arc` on `!Send`/`!Sync` types"

Closes https://github.com/rust-lang/rust/issues/114687. This is a clean revert of https://github.com/rust-lang/rust/pull/88936 + https://github.com/rust-lang/rust/pull/115210. The suggestion to Arc\<{Self}\> when Self does not implement Send is *always* wrong.

https://github.com/rust-lang/rust/pull/114842 is considering a way to make a more refined suggestion.

Rollup merge of #115294 - compiler-errors:cycle-err, r=oli-obk 
More precisely detect cycle errors from type_of on opaque

Not sure if this still needs work. Just putting it up for initial impressions, since it seems that a few people are frustrated with the increased error verbosity due to #113320.

Essentially we introduce a new sub-query for `type_of` specifically for opaques which returns a value that is able to distinguish "has errors" from "due to cycle recovery".

Fixes #115188

Rollup merge of #114924 - Zalathar:tidy-tests, r=Mark-Simulacrum 
coverage: Tidy up `run-coverage` tests in several small ways

Prior to #114875 (anonymized line numbers), these tests were very sensitive to lines being added/removed, since doing so would change the line numbers in every subsequent line of output. Therefore they ended up with a few small style issues that weren't worth the hassle of fixing.

Now that we can freely rearrange lines without needing to re-bless the entire output, we can tidy up the tests in various trivial ways.

have been deliberate.

4da38c31d2 Tidy up some awkwardly-placed comments in tests 
Prior to #114875, these tests were very sensitive to lines being added/removed,
so the migration to `run-coverage` in #112300 tried hard to avoid disturbing
the existing line numbers. That resulted in some awkward reshuffling when
certain comments/directives needed to be added or moved.

Now that we don't have to worry about preserving line numbers, we can rearrange
those comments into a more conventional layout.

thread caused non-unwinding panic. aborting.
```
If we also land https://github.com/rust-lang/rust/pull/115020, the 2nd backtrace disappears, hopefully making the "panic in a destructor during cleanup" easier to see.

Fixes https://github.com/rust-lang/rust/issues/114954.

Rollup merge of #115169 - RalfJung:do-not-ignore-debug, r=cjgillot 
remove some unnecessary ignore-debug clauses

ignore-debug is only needed when the debug assertions *in the standard library* somehow affect the test. This can happen with inlining but otherwise should be rare. ignore-debug is problematic since PR CI is only run with debug assertions.

r? `@cjgillot` since it looks like you added most of these

Rollup merge of #115151 - rcvalle:rust-cfi-fix-115150, r=compiler-errors 
Fix CFI: f32 and f64 are encoded incorrectly for cross-language CFI

Fix #115150 by encoding f32 and f64 correctly for cross-language CFI. I missed changing the encoding for f32 and f64 when I introduced the integer normalization option in #105452 as integer normalization does not include floating point. `f32` and `f64` should be always encoded as `f` and `d` since they are both FFI safe when their representation are the same (i.e., IEEE 754) for both the Rust compiler and Clang.
