Fix#120178.
internal: `tracing` improvements and followups
Hi folks! Building on https://github.com/rust-lang/rust-analyzer/pull/16394, I've got a few small tweaks:
- Removed the accidental `mod.rs` usage that I introduced.
- Removed a panic in `pat_analysis.rs`.
- Recorded the event kind in `handle_event` to better distinguish what _kind_ of event is being handled.
- Did a small refactor of `hprof` to have somewhat more linear control flow, and more importantly, write the recorded fields to the output.
The end result is the following:
<img width="1530" alt="A screenshot of Visual Studio Code on a Mac. `hprof.rs` is open, with " src="https://github.com/rust-lang/rust-analyzer/assets/2067774/bd11dde5-b2da-4774-bc38-bcb4772d1192">
Since the only use of `TypeCx::bug` is in `Constructor::is_covered_by`,
it is tempting to return `false` instead of `Err()`, but that would
cause "non-exhaustive match" false positives.
Update the library paths to correctly refer to libdemo{1,2}_hexagon
and switch to the release build instead.
Update references to libstandalone to the specific G0/PIC archive instead.
rustdoc: Correctly handle attribute merge if this is a glob reexport
Fixes#120487.
The regression was introduced in https://github.com/rust-lang/rust/pull/113091. Only non-glob reexports should have been impacted.

Don't hash lints differently to non-lints.
`Diagnostic::keys`, which is used for hashing and equating diagnostics, has a surprising behaviour: it ignores children, but only for lints. This was added in #88493 to fix some duplicated diagnostics, but it doesn't seem necessary any more.
This commit removes the special case and only four tests have changed output, with additional errors. And those additional errors aren't exact duplicates, they're just similar. For example, in src/tools/clippy/tests/ui/same_name_method.rs we currently have this error:
```
error: method's name is the same as an existing method in a trait
--> $DIR/same_name_method.rs:75:13
|
LL | fn foo() {}
| ^^^^^^^^^^^
|
note: existing `foo` defined here
--> $DIR/same_name_method.rs:79:9
|
LL | impl T1 for S {}
| ^^^^^^^^^^^^^^^^
```
and with this change we also get this error:
```
error: method's name is the same as an existing method in a trait
--> $DIR/same_name_method.rs:75:13
|
LL | fn foo() {}
| ^^^^^^^^^^^
|
note: existing `foo` defined here
--> $DIR/same_name_method.rs:81:9
|
LL | impl T2 for S {}
|
```
I think printing this second argument is reasonable, possibly even preferable to hiding it. And the other cases are similar.

Fix#40120.
std: thread_local::register_dtor fix proposal for FreeBSD.
following-up 5d3d347 commit, rust started to spin
__cxa_thread_call_dtors warnings even without any TLS usage. using instead home made TLS destructor handler `register_dtor_fallback`.
