Remove deferred sized checks (make them eager)
Improves diagnostics spans... this doesn't seem to be the case anymore:
```rust
// Some additional `Sized` obligations badly affect type inference.
// These obligations are added in a later stage of typeck.
pub(super) deferred_sized_obligations:
RefCell<Vec<(Ty<'tcx>, Span, traits::ObligationCauseCode<'tcx>)>>,
```
Migrate emoji identifier diagnostics to `SessionDiagnostic` in rustc_interface
* Migrate emoji identifier diagnostics to `interface_ferris_identifier` and `interface_emoji_identifier`.
This is my first PR! I'm learning how to migrate these diagnostics. Thanks in advance.

Pass +atomics-32 feature for {arm,thumb}v4t-none-eabi
Similar to 89582e8193, but for ARMv4t.
Pre-v6 ARM target does not have atomic CAS, except for Linux and Android where atomic CAS is provided by compiler-builtins. So, there is a similar issue as thumbv6m.
I have confirmed that enabling the `atomics-32` target feature fixes the problem in the project affected by this issue. (https://github.com/taiki-e/portable-atomic/pull/28#discussion_r946604136)
Closes#100619

unwind: don't build dependency when building for Miri
This is basically re-submitting https://github.com/rust-lang/rust/pull/94813.
In that PR there was a suggestion to instead have bootstrap set a `RUST_CHECK` env var and use that rather than doing something Miri-specific. However, such an env var would mean that when switching between `./x.py check` and `./x.py build`, the build script gets re-run each time, which doesn't seem good. So I think for now checking for Miri probably causes fewer problems.

Do not report cycle error when inferring return type for suggestion
The UI test is a good example of a case where this happens. The cycle is due to needing the value of the return type `-> _` to compute the variances of items in the crate, but then needing the variances of the items in the crate to do typechecking to infer what `-> _`'s real type is.
Since we're already gonna emit an error in astconv, just delay the cycle bug as an error.
triagebot: add translation-related mention groups
- Move some code around so that triagebot can ping relevant parties when translation logic is modified.
- Add mention groups to triagebot for translation-related files/folders.
- Auto-label pull requests with changes to translation-related files/folders with `A-translation`.

Rustdoc json tests: New @hasexact test command
Alot of the time, we wanted to assert that a module had an exact set of items. Most of the time this was done by asserting that the ```@count``` of the module was `n`, and then doing `n` ```@has``` checks on the module.
This was tedious, so often shortcuts were done.
This PR adds a new command to jsondocck to allow consistently expressing this behavior, and then uses it to clean up the tests.

No functional changes intended.
LLVM commit 633f5663c3 removed `createWriteThinLTOBitcodePass`.
This adapts PassWrapper similarly to the example mentioned upstream: 633f5663c3.
Simple Clamp Function
I thought this was more robust and easier to read. I also allowed this function to return early in order to skip the extra bound check (I'm sure the difference is negligible). I'm not sure if there was a reason for binding `self` to `x`; if so, please correct me.

Add `IpDisplayBuffer` helper struct.
This removes the dependency on `std::io::Write` for implementing `Display`, allowing it to be moved to `core` as proposed in https://github.com/rust-lang/rfcs/pull/2832.
