Add regression tests for const-generic inherent associated types
Fixes#109759.
The tests are no longer failing since #96840 which was merged recently (#109410 is no longer necessary for them).
`@rustbot` label F-inherent_associated_types
Improve tests for #110138
These should live in rustdoc-json, not rustdoc-ui, so we can run assertions, and not just check there's no ICE
CC #100515, as we never document this suite
r? rustdoc
Replace `yes` command by `while-echo` in test `tests/ui/process/process-sigpipe.rs`
The `yes` command is not available on all platforms.
Fixes#108596.
Inviting `@mvf` as he contributed to this patch. Thanks! This issue has been discussed in https://github.com/rust-lang/rust/pull/106673 but was moved to #108596 to get going.

Notes about the comments https://github.com/rust-lang/rust/pull/106673#discussion_r1117324265:
- The `echo` command is `/proc/boot/echo` (not built-in)
- `/bin/sh` is a symlink to `/proc/boot/ksh`
```sh
# ls -l /bin/sh /proc/boot/ksh /proc/boot/echo
lrwxrwxrwx 1 root root 14 Mar 20 07:52 /bin/sh -> /proc/boot/ksh
-r-xr-xr-x 1 root root 9390 Sep 12 2022 /proc/boot/echo
-r-xr-xr-x 1 root root 308114 Sep 12 2022 /proc/boot/ksh
```
They're semantically the same, so this means the backends don't need to handle the intrinsic and means fewer MIR basic blocks in pointer arithmetic code.
Use `?0` notation for ty/ct/int/float/region vars
Aligns the notation for infer vars that T-types and friends most often uses for inference variables with the notation in the compiler (which is kinda a sigil nightmare IMO: `_#`) by adopting `?0` style infer vars.
This mostly affects debug output since verbose infer vars shouldn't show up in user-facing places.
Does this need an MCP? It's debug output, so I'm thinking no, but happy to open one. 🤔

Consider polarity in new solver
It's kinda ugly to have a polarity check in all of the builtin impls -- I guess I could consider the polarity at the top of assemble-builtin but that would require adding a polarity fn to `GoalKind`...
🤷 putting this up just so i dont forget, since it's needed to bootstrap core during coherence (this alone does not allow core to bootstrap though, additional work is needed!)

Add `intrinsics::transmute_unchecked`
This takes a whole 3 lines in `compiler/` since it lowers to `CastKind::Transmute` in MIR *exactly* the same as the existing `intrinsics::transmute` does, it just doesn't have the fancy checking in `hir_typeck`.
Added to enable experimenting with the request in <https://github.com/rust-lang/rust/pull/106281#issuecomment-1496648190> and because the portable-simd folks might be interested for dependently-sized array-vector conversions.
It also simplifies a couple places in `core`.
See also https://github.com/rust-lang/rust/pull/108442#issuecomment-1474777273, where `CastKind::Transmute` was added having exactly these semantics before the lang meeting (which I wasn't in) independently expressed interest.
rustdoc: clean up settings.css and settings.js
`handleKey` was added in 9dc5dfb975 and 704050da23 because the browser-native checkbox was `display: none`, breaking native keyboard accessibility.
The native checkbox is now merely `appearance: none`, which does not turn off [behavior semantics], so JavaScript to reimplement it isn't needed any more.
[behavior semantics]: https://w3c.github.io/csswg-drafts/css-ui/#appearance-semantics
The other, one line change to settings.css is follow-up to #110205
Remove the size of locals heuristic in MIR inlining
This heuristic doesn't necessarily correlate to complexity of the MIR Body. In particular, a lot of straight-line code in MIR tends to never reuse a local, even though any optimizer would effectively reuse the storage or just put everything in registers. So it doesn't even necessarily make sense that this would be a stack size heuristic.
So... what happens if we just delete the heuristic? The benchmark suite improves significantly. Less heuristics better?

Run various queries from other queries instead of explicitly in phases
These are just legacy leftovers from when rustc didn't have a query system. While there are more cleanups of this sort that can be done here, I want to land them in smaller steps.
This phased order of query invocations was already a lie, as any query that looks at types (e.g. the wf checks run before) can invoke e.g. const eval which invokes borrowck, which invokes typeck, ...
