Show mode_t as octal in std::fs Debug impls
Example:
```rust
fn main() {
println!("{:?}", std::fs::metadata("Cargo.toml").unwrap().permissions());
}
```
- Before: `Permissions(FilePermissions { mode: 33204 })`
- ~~After: `Permissions(FilePermissions { mode: 0o100664 })`~~
- After: `Permissions(FilePermissions { mode: 0o100664 (-rw-rw-r--) })`
~~I thought about using the format from `ls -l` (`-rw-rw-r--`, `drwxrwxr-x`) but I am not sure how transferable the meaning of the higher bits between different unix systems, and anyway starting the value with a leading negative-sign seems objectionable.~~

According to <https://caniuse.com/?search=svg%20favicon>,
SVG favicons are supported in everything but Safari.
When I actually try it in Safari, it's downloading all
three favicons, and nothing looks different when I disable
the 16x16 one.
<https://dev.to/masakudamatsu/favicon-nightmare-how-to-maintain-sanity-3al7>,
which is linked from caniuse above, recommends an ico.
However, the reason they recommend it is the apps that
only support /favicon.ico exactly, and rustdoc can't assume
it will be installed to the site root, so it's unfortunately
up to the webmaster to make sure it's set up.
async closure coroutine by move body MirPass refactoring
Unsure about the last commit, but I think the other changes help in simplifying the control flow
Store all args in the unsupported Command implementation
This allows printing them in the Debug impl as well as getting them again using the get_args() method. This allows programs that would normally spawn another process to more easily show which program they would have spawned if not for the fact that the target doesn't support spawning child processes without requiring intrusive changes to keep the args. For example rustc compiled to wasi will show the full linker invocation that would have been done.
Don't use bytepos offsets when computing semicolon span for removal
Causes problems when we recover confusable characters w/ a different byte width
Fixes#123607
Clean up tests/ui by removing `does-nothing.rs`
In [a previous PR](https://github.com/rust-lang/rust/pull/123297#issuecomment-2039887806), it was suggested that this test be removed:
> it's testing a basic diagnostic for an unknown variable (added over a decade ago for https://github.com/rust-lang/rust/issues/154) that is already covered by probably dozens or hundreds of other tests.
It was then suggested that [opening a new PR](https://github.com/rust-lang/rust/pull/123563#discussion_r1554654102) for this would be more organized.
I'm setting this as a draft, as:
1. The tests/ui directory is rather disorganized, a large quantity of tests are not even contained inside their own directories. This PR could turn into "clean up the UI tests directory", if I were to place everything into categories (for example, everything related to CLI flags could get placed in a cli directory).
2. This will have a merge conflict with #123563 should that get merged. I trust that _this time_, I won't run into [The Incident](https://github.com/rust-lang/rust/pull/123297#issuecomment-2041137569) while rebasing. Edit: Yay, I did it properly!
Unconditionally show update nightly hint on ICE
Instead of trying to guess if a update nightly hint should be shown (by checking for system time, querying version and channel info etc.), just show the update nightly hint for nightly compilers. This avoids breaking tests that match on ICE test outputs on nightly/dev channels.
> Another issue is that the outdated nightly hint triggers for ICE tests, causing a mismatch with the test expectation. There doesn't seem to be any env var to suppress this.
See <https://rust-lang.zulipchat.com/#narrow/stream/326414-t-infra.2Fbootstrap/topic/stage0.20compiletest.20broken/near/425543681> for context.

When suggesting a type on inference error, do not use `{closure@..}`.
Instead, replace with an appropriate `fn` ptr.
On the error message, use `short_ty_string` and write long types to
disk.

Fix#123630.
Unify the output of `suggest_assign_value` and `ty_kind_suggestion`.
Ideally we'd make these a single function, but doing so would likely require modify the crate dependency tree.
This commit does three things:
1. replaces (the last remaining) never true cfgs by the FALSE cfg
2. fix derive-helper-configured.rs (typo in directive)
3. and comment some current unused #[cfg_attr] (missing revisions)
I added this back in 111999, but I no longer think it's a good idea
- It had to get scaled back to only power-of-two things to not break a bunch of targets
- LLVM seems to be getting better at memcpy removal anyway
- Introducing vector instructions has seemed to sometimes (115515) make autovectorization worse
So this removes it from the codegen crates entirely, and instead just tries to use <https://doc.rust-lang.org/nightly/nightly-rustc/rustc_codegen_ssa/traits/builder/trait.BuilderMethods.html#method.typed_place_copy> instead of direct `memcpy` so things will still use load/store for immediates.
