Remove unnecessay .report() on ExitCode
Since #93442, the return type is `ExitCode` anyway so there's no need to do a conversion using `.report()` (which is now just a no-op).
move processing of `source_scope_data` into `MutVisitor`'s impl of `Integrator` when inline
This PR fixes the FIXME in the inline mir-opt which moves processing of `source_scope_data` into `MutVisitor`'s impl of `Integrator` when inline
`simplify_type` improvements and cursed docs
the existing `TreatParams` enum pretty much mixes everything up. Not sure why this looked right to me in #94057
This also includes two changes which impact perf:
- `ty::Projection` with inference vars shouldn't be treated as a rigid type, even if fully normalized
- `ty::Placeholder` only unifies with itself, so actually return `Some` for them

This alters the diagnostics a bit, as the trait method is still stable.
The only thing this check does is ensure that compilation fails if a
trait implementation is declared const-stable.
Rather than deferring to const eval for checking if a trait is const, we
now check up-front. This allows the error to be emitted earlier, notably
at the same time as other stability checks.
Also included in this commit is a change of the default const stability
level to UNstable. Previously, an item that was `const` but did not
explicitly state it was unstable was implicitly stable.
Remove libstd's calls to `C-unwind` foreign functions
Remove all libstd and its dependencies' usage of `extern "C-unwind"`.
This is a prerequiste of a WIP PR which will forbid libraries calling `extern "C-unwind"` functions to be compiled in `-Cpanic=unwind` and linked against `panic_abort` (this restriction is necessary to address soundness bug #96926).
Cargo will ensure all crates are compiled with the same `-Cpanic` but the std is only compiled `-Cpanic=unwind` but needs the ability to be linked into `-Cpanic=abort`.
Currently there are two places where `C-unwind` is used in libstd:
* `__rust_start_panic` is used for interfacing to the panic runtime. This could be `extern "Rust"`
* `_{rdl,rg}_oom`: a shim `__rust_alloc_error_handler` will be generated by codegen to call into one of these; they can also be `extern "Rust"` (in fact, the generated shim is used as `extern "Rust"`, so I am not even sure why these are not, probably because they used to `extern "C"` and was changed to `extern "C-unwind"` when we allow alloc error hooks to unwind, but they really should just be using Rust ABI).
For dependencies, there is only one `extern "C-unwind"` function call, in `unwind` crate. This can be expressed as a re-export.
More dicussions can be seen in the Zulip thread: https://rust-lang.zulipchat.com/#narrow/stream/210922-project-ffi-unwind/topic/soundness.20in.20mixed.20panic.20mode

Move some settings DOM generation out of JS
The first commit reduce the JS size a bit by moving some DOM content generation into the HTML file directly.
The second commit is an update of the `browser-ui-test` version which improves `wait-for-*` command (if the element doesn't exist, it'll wait for it instead of failing).

Switch CI bucket uploads to intelligent tiering
We currently upload approximately 166 GB/day into this bucket (estimate based on
duration of storage and total current size). My estimate is that this change
should decrease our costs (which are currently in credits) and is in the worst
case (if all objects are brought into hot storage due to unanticipated frequent
access) only going to add an additional ~$4 to the monthly bill. If access is
rare (as expected) to most objects then we expect to save approximately
~$350/month (after this change takes full effect in ~168 days).

You can test this by (say) adding `foobar = 42` to Clippy's root `clippy.toml` file, and running `cargo run --bin cargo-clippy`.
Note that, to get the terminal width, this PR adds `termize` as a dependency to `cargo-clippy`. However, `termize` is also [how `rustc_errors` gets the terminal width](481db40311/compiler/rustc_errors/src/emitter.rs (L1607)). So, hopefully, this is not a dealbreaker.
