Add `get_line` confusable to `Stdin::read_line()`
This pull request resolves https://github.com/rust-lang/rust/issues/131091
---
I've updated tests for `tests/ui/attributes/rustc_confusables_std_cases` in order to verify this change is working as intended.
Before I submitted this pull request, I had a pull request to my local fork. If you're interested in seeing the conversation on that PR, go to https://github.com/JakenHerman/rust/pull/1.

**Testing**:
Run `./x.py test tests/ui/attributes/rustc_confusables_std_cases.rs`
This code can sometimes witness malformed coverage attributes in builds that
are going to fail, so use `span_delayed_bug` to avoid an inappropriate ICE in
that case.
impl `Default` for `HashMap`/`HashSet` iterators that don't already have it
This is a follow-up to #128261 that isn't included in that PR because it depends on:
* [x] rust-lang/hashbrown#542 (`Default`)
* [x] `hashbrown` release containing above
It also wasn't included in #128261 initially and should have its own FCP, since these are also insta-stable.
Changes added:
* `Default for hash_map::{Iter, IterMut, IntoIter, IntoKeys, IntoValues, Keys, Values, ValuesMut}`
* `Default for hash_set::{Iter, IntoIter}`
Changes that were added before FCP, but are being deferred to later:
* `Clone for hash_map::{IntoIter, IntoKeys, IntoValues} where K: Clone, V: Clone`
* `Clone for hash_set::IntoIter where K: Clone`

Fix `target_vendor` for `aarch64-nintendo-switch-freestanding`
Previously set to `target_vendor = "unknown"`, but Nintendo is clearly the vendor of the Switch, and is also reflected in the target name itself.

Add unstable support for outputting file checksums for use in cargo
Adds an unstable option that appends file checksums and expected lengths to the end of the dep-info file such that `cargo` can read and use these values as an alternative to file mtimes.
This PR powers the changes made in this cargo PR https://github.com/rust-lang/cargo/pull/14137
Here's the tracking issue for the cargo feature https://github.com/rust-lang/cargo/issues/14136.
std: make `thread::current` available in all `thread_local!` destructors
... and thereby allow the panic runtime to always print the right thread name.
This works by modifying the TLS destructor system to schedule a runtime cleanup function after all other TLS destructors registered by `std` have run. Unfortunately, this doesn't affect foreign TLS destructors, `thread::current` will still panic there.
Additionally, the thread ID returned by `current_id` will now always be available, even inside the global allocator, and will not change during the lifetime of one thread (this was previously the case with key-based TLS).
The mechanisms I added for this (`local_pointer` and `thread_cleanup`) will also allow finally fixing #111272 by moving the signal stack to a similar runtime-cleanup TLS variable.
Update hashbrown to 0.15 and adjust some methods
This PR updates `hashbrown` to 0.15 in the standard library and adjust some methods as well as removing some as they no longer exists in Hashbrown it-self.
- `HashMap::get_many_mut` change API to return array-of-Option
- `HashMap::{replace_entry, replace_key}` are removed, FCP close [already finished](https://github.com/rust-lang/rust/issues/44286#issuecomment-2293825619)
- `HashSet::get_or_insert_owned` is removed as it no longer exists in hashbrown

interpret: always enable write_immediate sanity checks
Writing a wrongly-sized scalar somewhere can have quite confusing effects. Let's see how expensive it is to catch this early.
add caching to most type folders, rm region uniquification
Fixes the new minimization of the hang in nalgebra and nalgebra itself :3
this is a bit iffy, especially the cache in `TypeRelating`. I believe all the caches are correct, but it definitely adds some non-local complexity in places. The first commit removes region uniquification, reintroducing the ICE from https://github.com/rust-lang/trait-system-refactor-initiative/issues/27. This does not affect coherence and I would like to fix this by introducing OR-region constraints
r? `@compiler-errors`
The `armv7a-kmc-solid_asp3-eabi` and `armv7a-kmc-solid_asp3-eabihf`
targets clearly have the ABI in their name, so it should also be exposed
in Rust's `target_abi` cfg variable.
A simplification that doesn't impact the epoll implementation's logic.
It is not necessary to clone the ready_list before reading its
`is_empty` state.
This avoids the clone step but more importantly avoids the invisible
drop step of the clone.
This adds a VClock to the epoll implementation's ready_list
and has this VClock synced from the thread that updates
an event in the ready_list and then has the VClocks of any
threads being made runnable again, out of the calls to
epoll_wait, synced from it.
A couple of instructions were left over from an earlier rebase
it would seem. They don't impact the logic but the ready_list type
is about to change in the next commit.
Rather than modify one of these lines in the commit that changes
ready_list, only to have these lines removed later on, remove them now.
They don't impact the tests results.

Replace zero-width whitespace with a visible `\` in the PR template
People (incl. myself) tried to copy the `r?` which had an invisible zero-width whitespace (meaning it was actually more like `r⌴?`), causing rustbot to not recognize the instruction, and which makes it difficult to figure out why it didn't work.
This PR replaces the zero-width whitespace with a visible `\` alongside a comment to remove the `\`. It's a bit less "visual", but at least it's visible why the rustbot assignment doesn't work.
mpmc doctest: make sure main thread waits for child threads
Currently, chances are half the test is not executed because the main thread exits while the other threads are still working.
