Normalize types and consts in MIR opts.
Some passes were using a non-RevealAll param_env, which is needlessly restrictive in mir-opts.
As a drive-by, we normalize all constants, since just normalizing their types is not enough.
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.
Group some sections of our logs in github actions
This makes logs a little bit more readable as you can now collapse all the parts that don't interest you (and they get collapsed automatically)
Obviously there's a lot more sites where we can/need to do this, too, but this is already helpful imo

Impl `Copy` for most HIR types
This simplifies the invocation of the `arena_types` macro and probably
makes working with HIR nicer in general.
Based on #109588
Fix printing native CPU on cross-compiled compiler.
If `rustc` is cross-compiled from a different host, then the "native" entry in `rustc --print=target-cpus` would not appear. There is a check in the printing code that will avoid printing the "native" entry if the user has passed `--target`. However, that check was comparing the `--target` value with the `LLVM_TARGET_TRIPLE` which is the triple of the host that `rustc` was built on (the "build" target in Rust lingo), not the target it was being built for (the "host" in Rust lingo). This fixes it to use the target that LLVM was built for (which I'm pretty sure this is the correct function to determine that).
This fixes the cpu listing for aarch64-apple-darwin which is built on CI using the x86_64-apple-darwin host.
stop `x fmt` formatting untracked directories
I don't think there's anything else to do? I've confirmed that you get a "skip untracked path foo/ during rustfmt invocations" for the alternative build directory.

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, ...
Turn on ConstDebugInfo pass.
Split from https://github.com/rust-lang/rust/pull/103657
Moving those constant into debuginfo allows to shrink the number of locals and the actual size of the MIR body.
Add `items_after_test_module` lint
Resolves task *3* of #10506, alongside *1* resolved at #10543 in an effort to help standarize a little bit more testing modules.

changelog:[`items_after_test_module`]: Added the lint.
make [`len_zero`] lint not spanning over parenthesis
sorry it should be a quick fix but I was caught up by other stuffs last couple weeks 🤦♂️

Limit read size in `File::read_to_end` loop
Fixes#110650.
Windows file reads have perf overhead that's proportional to the buffer size. When we have a reasonable expectation that we know the file size, we can set a reasonable upper bound for the size of the buffer in one read call.
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`.
