Use details tag for trait implementors.
Part of #83332 and following on from #83337 and #83355.
This removes one category of JS-generated toggles (implementors), and replaces them with a `<details>` tag. This simplifies the JS, and fixes some bugs where things that were supposed to be hidden by the toggle were not hidden. Compare https://hoffman-andrews.com/rust/details-implementors/std/io/trait.Read.html#impl-Read vs https://doc.rust-lang.org/nightly/std/io/trait.Read.html#implementors.
This introduces a `left: -23px` to put the toggle in the correct place, matching the current style for `.collapse-toggle`.
It's worth noting this introduces a slight behavior change: since the entire line is now a `<summary>`, any part of the line is clickable. So for instance, in `impl Read for File`, clicking `impl` or `for` will collapse / expand the docs. Clicking `Read` or `File` still links to the appropriate documentation as before.

bootstrap: use bash on illumos to run install scripts
The default illumos shell ("sh" in the default PATH) is ksh93, rather
than bash, and does not support constructs like "local" that came from
bash. The bootstrap function for invoking "install.sh" scripts should
use "bash" explicitly there to avoid issues.

doc/platform-support: clarify UEFI support
Add missing information on what standard-library features are supported by the UEFI targets.
All current UEFI targets (which is i686 and x86_64) only support no_std cross-compilations. `std` support has not been worked on and is unlikely to emerge anytime soon, due to the much restricted environment that UEFI provides.

rustdoc: Convert sub-variant toggle to HTML
Instead of creating a JS toggle, this injects details/summary for
sub-variants of enums. This also fixes the CSS so that the toggle button
does not jump when expanding/collapsing.
Takes inspiration from #83337 and should be considered part of #83332. Not quite sure if the `.sub-variant` selectors could be further simplified? AFAICS it is only used in that place, and that does not seem to allow any recursion.

rustc: Use LLVM's new saturating float-to-int intrinsics
This commit updates rustc, with an applicable LLVM version, to use
LLVM's new `llvm.fpto{u,s}i.sat.*.*` intrinsics to implement saturating
floating-point-to-int conversions. This results in a little bit tighter
codegen for x86/x86_64, but the main purpose of this is to prepare for
upcoming changes to the WebAssembly backend in LLVM where wasm's
saturating float-to-int instructions will now be implemented with these
intrinsics.
This change allows simplifying a good deal of surrounding code, namely
removing a lot of wasm-specific behavior. WebAssembly no longer has any
special-casing of saturating arithmetic instructions and the need for
`fptoint_may_trap` is gone and all handling code for that is now
removed. This means that the only wasm-specific logic is in the
`fpto{s,u}i` instructions which only get used for "out of bounds is
undefined behavior". This does mean that for the WebAssembly target
specifically the Rust compiler will no longer be 100% compatible with
pre-LLVM 12 versions, but it seems like that's unlikely to be relied on
by too many folks.
Note that this change does immediately regress the codegen of saturating
float-to-int casts on WebAssembly due to the specialization of the LLVM
intrinsic not being present in our LLVM fork just yet. I'll be following
up with an LLVM update to pull in those patches, but affects a few other
SIMD things in flight for WebAssembly so I wanted to separate this change.
Eventually the entire `cast_float_to_int` function can be removed when
LLVM 12 is the minimum version, but that will require sinking the
complexity of it into other backends such as Cranelfit.

rustdoc: Remove most fields from ExternalCrate
Once https://github.com/rust-lang/rust/issues/84304 is fixed, I can get rid of ExternCrate altogether in favor of CrateNum, but in the meantime, this shrinks ExternalCrate quite a lot.
This might hurt compile-times; if it does, I can add `primitive` and `keyword` queries. I expect this to improve compilemem.
Helps with https://github.com/rust-lang/rust/issues/76382.

rustdoc: Hide `#text` in doc-tests
Since `#![attr]` and `#[attr]` are the only valid syntax that start with `#`, we can just special case those two tokens.

It's always `tcx.crate_name(LOCAL_CRATE)`, it doesn't need to be passed
in separately.

Use arrayvec 0.7, drop smallvec 0.6
With the arrival of min const generics, many alt-vec libraries have
updated to use it in some way and arrayvec is no exception. Use the
latest with minor refactoring.
Also, rustc_workspace_hack is the only user of smallvec 0.6 in the
entire tree, so drop it.

Check for intrinsics before coercing to a function pointer
Return an error if coercing function items / non-capturing closures
to a common function pointer type would require reifying an intrinsic.

bootstrap: Restore missing --bulk-dirs for rust-docs, rustc-docs
The `--bulk-dirs` argument was removed for rust-docs in commit c768ce138427b1844c1f6594daba9c0e33928032 and rustc-docs in commit 8ca46fc7a83734c9622f11f25d16b82316f44bcc (#79788), presumably by mistake; that slowed down installation of rust-docs from under a second to some twenty *minutes*. Restoring `--bulk-dirs` reverses this slowdown.
Fixes #80684.

Support `x.py doc std --open`
I usually run this command:
```
./x.py doc std --stage 1 --jobs 8
```
Then I gave a try to `--open` and realized it wasn't working. I finally realized it was simply because it was only handling paths starting with `library`. This PR allows to handle both kinds of paths.

Write Rustdoc titles like "x in crate::mod - Rust"
This makes Rustdoc titles for items be like "Widget in cratename::blah::foo - Rust". Titles for modules and other non-items are unchanged, and still read like "cratename::blah::foo - Rust". This makes managing several open Rustdoc tabs easier.
This also adds some tests for the new title behavior.
Closes #84371.
