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.

document `FromIterator for Vec` allocation behaviors
[t-libs discussion](https://rust-lang.zulipchat.com/#narrow/stream/259402-t-libs.2Fmeetings/topic/Meeting.202024-01-24/near/417686526) about #120091 didn't reach a strong consensus, but it was agreed that if we keep the current behavior it should at least be documented even though it is an implementation detail.
The language is intentionally non-committal. The previous (non-existent) documentation permits a lot of implementation leeway and we want retain that. In some cases we even must retain it to be able to rip out some code paths that rely on unstable features.
pattern_analysis: cleanup the contexts
This cleans up a bit the various `*Ctxt`s I had left lying around. As a bonus this made it possible to make `PatternColumn` public. I don't have a use for that yet but that could come useful.
`UsefulnessCtxt` looks useless right now but I'll be adding a field or two in subsequent PRs.

Bump Fuchsia, build tests, and use 8 core bots
- Build Fuchsia on 8 cores instead of 16
- Skip building cranelift for Fuchsia
- Bump Fuchsia (includes building tests)
This includes a change to the upstream build_fuchsia_from_rust_ci script that builds a minimal set of tests, to improve coverage on this builder. This would have caught https://github.com/rust-lang/rust-clippy/issues/11952 and #119593.
See prior discussion on #119400 about building on 8 cores instead of 16. This PR combines changes from that and #119399, plus clean up.

Further improve `space_between`
`space_between` is used by `print_tts` to decide when spaces should be put between tokens. This PR improves it in two ways:
- avoid unnecessary spaces before semicolons, and
- don't omit some necessary spaces before/after some punctuation symbols.

Disable packed/unpacked options for riscv linux/android.
Other riscv targets already only have the off option.
The packed/unpacked options might be supported in the future.

Normalize region obligation in lexical region resolution with next-gen solver
This normalizes region obligations when we `resolve_regions`, since they may be unnormalized with deferred projection equality.
It's pretty hard to add tests that exercise this without also triggering MIR borrowck errors (because we don't normalize there yet). I've added one test with two revisions that should test that we both 1. normalize region obligations in the param env, and 2. normalize registered region obligations during lexical region resolution.
internal: Undo special bracket classification for attributes in vscode config
I changed this thinking the `#` could be considered part of the bracket but on second though I don't think that's quite right in general.
Fixes https://github.com/rust-lang/rust-analyzer/issues/16449
internal: add some `tracing` to {Request, Notification}Dispatch
Some of the tracing config would need to be changed in order to benefit more from this (especially `.with_span_events(FmtSpan::CLOSE)`), which provides span events like the following:
```
2024-01-18T02:41:06.675779Z INFO request{method="textDocument/codeLens" request_id=RequestId(I32(17))}: rust_analyzer::dispatch: close time.busy=61.8µs time.idle=5.29µs
```
I dunno if y'all need `LoggerFormatter` in here, but if you don't, I'd be happy to yeet it out of rust-analyzer. In any case, this provided a pretty decent amount of information in the logs, and I can expand this as needed or we can land this PR and expand later.
This commit also adds `tracing` to NotificationDispatcher/RequestDispatcher,
bumps `rust-analyzer-salsa` to 0.17.0-pre.6, `always-assert` to 0.2, and
removes the homegrown `hprof` implementation in favor of a vendored
tracing-span-tree.
