get rid of a whole bunch of unnecessary rustc_const_unstable attributes
In general, when a `const fn` is still unstable, it doesn't need a `#[rustc_const_unstable]` attribute. The only exception is functions that internally use things that can't be used in stable const fn yet.
So this gets rid of a whole bunch of `#[rustc_const_unstable]` in libcore.
Add `--print host-tuple` to print host target tuple
People often parse `-vV` output to get to the host tuple, which is annoying to do. It's easier to just get it directly.
I called it "host-tuple" instead of "host" because it's clearer that it's just the target name. I'm open to different names, but I think this one is fine.
a quick GitHub search for `'^host` reveals many instances of people doing the parsing, for example:
68e0ca57cd/README.md (L369)0e38473b0c/main.sh (L96)8a3553b865/README.md (L625)43f3ec3970/do.sh (L35)
needs a compiler FCP. I could also do an MCP but I think just an FCP here makes the most sense.

* Remove redundant wording
* Introduce trait diff highlighting logic and use it
* Fix incorrect "long type written to path" logic (can be split off)
* Point at tail expression in more cases in E0277
* Avoid long primary span labels in E0277 by moving them to a `help`
Fix#132013.
There are individual commits that can be their own PR. If the review load is too big, happy to split them off.
As with ab5583ed1e, we had been explicitly
passing defaults whose type have changed. Rather than do an ifdef, we
simply rely on the defaults.
@rustbot label: +llvm-main
We don't see a reason to explicitly pass the default here, so just use
the default instead of explicitly passing it and needing an ifdef.

miri: Directly use rustc_abi
I tried to make this a PR to the miri repo for funsies. Ironically, the integration flow meant that it would use a too-old toolchain hash, and I didn't understand the build system there enough to want to manually fiddle with the hashes.

Improve display of clippy lints page when JS is disabled
There is no point in displaying the settings menu and the filters if JS is disabled. So in this case, this PR simply hides it:
For the theme handling though, I need to send a fix to mdBook first. But once done, it'll look as expected (dark if system is in dark mode).

Remove unintended link
Since `#[link_section]` is enclosed in braces, it was being confused with a link during docs compilation.
This caused compilation to fail when running `x dist` since it emitted a warning regarding broken links.
Fix type reference in documents which was being confused with html tags.
Running `x dist` was failing due to it invoking commands with `-D warnings`, which emitted a warning about unclosed html tags.
