uefi: process: Fix args
- While working on process env support, I found that args were currently broken. Not sure how I missed it in the PR, but well here is the fix.
- Additionally, no point in adding space at the end of args.
Render pattern types nicely in mir dumps
avoid falling through to the fallback rendering that just does a hex dump

Reject unsound toggling of Arm atomics-32 target feature
This target feature has the same semantics as RISC-V `forced-atomics` target feature that already marked as Forbidden (f5ed0cb217) and toggling it can cause ABI incompatibility.
2f348cb7ce/compiler/rustc_target/src/target_features.rs (L479-L483)
[Comment on feature definition in LLVM](7109f52197/llvm/lib/Target/ARM/ARMFeatures.td (L572-L574)) also says:
> Code built with this feature is not ABI-compatible with code built without this feature, if atomic variables are exposed across the ABI boundary.

GCI: Don't try to eval / collect mono items inside overly generic free const items
Fixes#136156. Thanks for the pointers, errs!
There's one (preexisting) thing of note (maybe?). There's a difference between `const _: () = panic!();` and `const _<'a>: () = panic!();`: The former is a pre-mono error, the latter is a post-mono error. For comparison, both `fn _f() { const { panic!() } }` and `fn _f<'a: 'a>() { const { panic!() } }` are post-mono errors.

rustdoc: add nobuild typescript checking to our JS
By nobuild, I mean that the type annotations are all [in comments], not in the "native" typescript syntax. This is a bit uglier, but it lets you rapid-prototype without tsc, works with all the native browser debugging tools, and keeps Node out of Rust's bootstrap chain.
[in comments]: https://news.ycombinator.com/item?id=35892250
This pull request mostly just adds ts-ignore annotations and type declarations. To actually take good advantage of typescript, we'll want to "burn down" this pile of unsafe code until we eventually have a version with almost none of these.
This PR also adds tsc to the mingw-check Dockerfile, so that it can't fall out of date like the Closure annotations did.

Deduplicate operand creation between scalars, non-scalars and string patterns
just something that felt duplicated and would make pattern type handling a bit more roundabout.

ABI-required target features: warn when they are missing in base CPU
Part of https://github.com/rust-lang/rust/pull/135408:
instead of adding ABI-required features to the target we build for LLVM, check that they are already there. Crucially we check this after applying `-Ctarget-cpu` and `-Ctarget-feature`, by reading `sess.unstable_target_features`. This means we can tweak the ABI target feature check without changing the behavior for any existing user; they will get warnings but the target features behave as before.
The test changes here show that we are un-doing the "add all required target features" part. Without the full #135408, there is no way to take a way an ABI-required target feature with `-Ctarget-cpu`, so we cannot yet test that part.

Add mermaid graphs of NLL regions and SCCs to polonius MIR dump
This PR expands the polonius MIR dump again with a couple of mermaid charts ported from the graphviz version:
- the NLL region graph
- and the NLL SCCs
I still have done zero visual design on this until now, but [here's](https://gistpreview.github.io/?fbbf900fed2ad21108c7ca0353456398) how it looks (i.e. still bad) just to give an idea of the result.

Rename `Piece::String` to `Piece::Lit`
This renames Piece::String to Piece::Lit to avoid shadowing std::string::String and removes "pub use Piece::*;".

error[E0596]: cannot borrow `*self.s` as mutable, as it is behind a `&` reference
--> $DIR/issue-38147-1.rs:17:9

LL | self.s.push('x');

Note the suggestion to add `mut` instead of replacing the entire `&self` with `&mut self`.
Apply LTO config to rustdoc
Before, the LTO configuration from `config.toml` was not applied to `rustdoc`. This provides a small perf. and binary size [win](https://github.com/rust-lang/rust/pull/112049#issuecomment-2605131041) for doc builds.
Since this is configured with Cargo profiles and not rustflags, it should not break tool build cache (https://github.com/rust-lang/rust/pull/131155). I tried to run `x test miri`, `x test rustdoc` and `x test miri` and nothing was rebuilt.

Flip the `rustc-rayon`/`indexmap` dependency order
[`rustc-rayon v0.5.1`](https://github.com/rust-lang/rustc-rayon/pull/14) added `indexmap` implementations that will allow `indexmap` to drop its own "internal-only" implementations.
(This is separate from `indexmap`'s implementation for normal `rayon`.)
Arbitrary self types v2: explain test.
The purpose of this test wasn't obvious, as ```@traviscross``` noted. Add a comment.
Confession: although this test was added to demonstrate this particular corner-case, I can no longer reproduce the original problem, even if I adjust `rustc` to do the "wrong" thing. I have spent several hours trying to adjust the case to trigger the "faulty" behavior with no success. This test may therefore not be as useful as it originally was. But it still seems worthwhile retaining as a regression test that we don't break things in these quirky circumstances. Ideally we'd find a new test which tests this behavior but I've failed to come up with one.
