Swap TargetOptions::linker_is_gnu default from false to true and update targets as appropriate.
#85274 gated the `--gc-sections` flag on targets that specified `linker_is_gnu` to stop us from passing it to incompatible linkers. But that had the unintended effect of the flag no longer being passed on targets for which it is valid and hence caused a regression in binary size. Given that most `ld`-style linkers are GNU compatible, this change flips our default for `linker_is_gnu` from false to true. That also means updating the targets that relied on the previous default:
* Apple
* Illumos
* L4Re (not sure about this one)
* MSVC
* NvtPtx
* Solaris

facepalm: operator precedence fail on my part.
This bug was only visible on mac. Also, print_step_rusage is a relatively new
internal feature, that is not heavily used, and has no tests. All of these
factors contributed to how this went uncaught this long. Thanks to Josh Triplett
for pointing it out!
Remove dead toggle JS code
Explanations on how I got there: I randomly saw `adjustToggle` while browsing through code, checked where it was called, put a `debugger;` instruction in it and checked on all pages while playing with settings and toggles. The breakpoint was never triggered. I then looked at `collapseNonInherent` (its grand-parent). In there, the breakpoint was triggered so I look at what was being done and in fact... nothing. So I simply removed it all, re-ran the tests and play with the UI. Everything is working as expected.
Better double check in case I forgot to check a case though, but if nothing has been left out, then it's a great cleanup once again. :)

Reset "focusedByTab" field when doing another search
Fixes https://github.com/rust-lang/rust/issues/85467.
The problem was simply that we forget to reset the `focusedByTab` field, which was still referring to removed DOM elements.

Adjust self-type check to require equality
When we encounter `SomeType::<X>::foo`, `self_ty` is `SomeType<X>` and the method is defined in an impl on `SomeType<A>`. Previously, we required simply that `self_ty <: impl_ty`, but this is too lax: we should require equality in order to use the method. This was found as part of unrelated work on never type stabilization, but also fixes one of the wf test cases.

PassWrapper: update for LLVM change D102093
In https://reviews.llvm.org/D102093 lots of things stopped taking the
DebugLogging boolean parameter. Mercifully we appear to always set
DebugPassManager to false, so I don't think we're losing anything by not
passing this parameter.
Windows implementation of feature `path_try_exists`
Draft of a Windows implementation of `try_exists` (#83186).
The first commit reorganizes the code so I would be interested to get some feedback on if this is a good idea or not. It moves the `Path::try_exists` function to `fs::exists`. leaving the former as a wrapper for the latter. This makes it easier to provide platform specific implementations and matches the `fs::metadata` function.
The other commit implements a Windows specific variant of `exists`. I'm still figuring out my approach so this is very much a first draft. Eventually this will need some more eyes from knowledgable Windows people.
Always produce sub-obligations when using cached projection result
See https://github.com/rust-lang/rust/issues/85360
When we skip adding the sub-obligations to the `obligation` list, we can affect whether or not the final result is `EvaluatedToOk` or `EvaluatedToOkModuloObligations`. This creates problems for incremental compilation, since the projection cache is untracked shared state.
To solve this issue, we unconditionally process the sub-obligations. Surprisingly, this is a slight performance *win* in many cases.
Clarify error returns from Mutex::try_lock, RwLock::try_read,
RwLock::try_write to make it more obvious that both poisoning
and the lock being already locked are possible errors.
