Don't ICE in `check_must_not_suspend_ty` for mismatched tuple arity
These expressions are just used for their spans, so make it best-effort here.

Sort lint_groups in no_lint_suggestion
The no_lint_suggestion routine passes a vector of lint group names to find_best_match_for_name. That routine depends on the sort order of its input vector, which matters in case multiple inputs are at the same Levenshtein distance to the target name.
However, no_lint_suggestion currently just passes lint_groups.keys() as input vector - this is sorted in hash value order, which is not guaranteed to be stable, and in fact differs between big- and little-endian host platforms, causing test failures on s390x.
To fix this, always sort the lint groups before using their names as input to find_best_match_for_name. In doing so, prefer non- deprecated lint group names over deprecated ones, and then use alphabetical order.

Refer to "Waker" rather than "RawWaker" in `drop` comment
In my view this is technically more correct as `Waker` actually implements `Drop` (which calls the `drop` method) whereas `RawWaker` does not.
str.lines() docstring: clarify that line endings are not returned
Previously, the str.lines() docstring stated that lines are split at line endings, but not whether those were returned or not. This new version of the docstring states this explicitly, avoiding the need of getting to doctests to get an answer to this FAQ.
Rename `assert_uninit_valid` intrinsic
It's not about "uninit" anymore but about "filling with 0x01 bytes" so the name should at least try to reflect that.
This is actually not fully correct though, as it does still panic for all uninit with `-Zstrict-init-checks`. I'm not sure what the best way is to deal with that not causing confusion. I guess we could just remove the flag? I don't think having it makes a lot of sense anymore with the direction that we have chose to go. It could be relevant again if #100423 lands so removing it may be a bit over eager.

The no_lint_suggestion routine passes a vector of lint group names
to find_best_match_for_name. That routine depends on the sort
order of its input vector, which matters in case multiple inputs
are at the same Levenshtein distance to the target name.
However, no_lint_suggestion currently just passes lint_groups.keys()
as input vector - this is sorted in hash value order, which is not
guaranteed to be stable, and in fact differs between big- and
little-endian host platforms, causing test failures on s390x.
To fix this, always sort the lint groups before using their names
as input to find_best_match_for_name. In addition, deprecated
lint groups should never be suggested, so filter those out.

Implement `From<bool>` for f32, f64
As is required for trait implementations, these are insta-stable. Given there is a release tomorrow and this needs FCP, I set 1.65 as the stable version.

LLVM does this itself since 606cb8548a1b7763e0c8489c5efe66803a7ede72,
and 14 is no longer the correct standard when building lld 16,
causing build failures.
This patch does the following:
- Refactor some repeated lines into a single one
- Split the `ungated_async_fn_caller` lint into multiple lines, and make
one of those lines only print out on nightly
- Use test revisions instead of copying an existing test
This patch fixes a regression, in which `#[track_caller]`, which was
previously a no-op, was changed to actually turn on the behavior. This
should instead only happen behind the `closure_track_caller` feature
gate.
Also, add a warning for the user to understand how their code will
compile depending on the feature gate being turned on or not.

Remove unused `check-stage2-T-arm-linux-androideabi-H-x86_64-unknown-linux-gnu` make rule
It's not used anywhere in CI, and it seems of questionable use. It was first added in 0e272de69f, which looks like it's just intended for CI, not as a user-facing feature.
Avoid going through the happy path in case of non-fn builtin calls
No functional change, just doing an early return. The removed comment is not applicable anymore, not every node needs type bindings in the error case. At best this would have been needed to avoid ICEs, but afaict this can't happen anymore today, as we do fallible checks.
