It's simpler and makes some benchmark run up to 1% faster. It also makes
`hir::ExprKind` more like `ast::ExprKind` (which underwent the
equivalent change in #55777).

[rustdoc] Fix crates filtering box not being filled
Currently, the filter crate box (at the left of the search input) is always empty. To get the number of keys of dictionary in JS, you need to call `Object.keys()` on it.

Simplify 'product' factorial example
This simplifies the [`factorial(n: 32)`](https://doc.rust-lang.org/std/iter/trait.Iterator.html#examples-46) implementation as example for the `Iterator::product()` function.
It currently uses unnecessary additional complexity.
Although very minimal, I do not want to include it in some other irrelevant PR.
Add core::iter::once_with()
Functions `iter::once()` and `iter::repeat()` construct iterators from values. The latter has the lazy variant `iter::repeat_with()`, but the former doesn't. This PR therefore adds `iter::once_with()`.
Another way to think of `iter::once_with()` is that it's a function that converts `FnOnce() -> T` into `Iterator<Item = T>`.
If this seems like a reasonable addition, I'll open a tracking issue and update the `#[feature(...)]` attributes.
forbid manually impl'ing one of an object type's marker traits
This shouldn't break compatibility for crates that do not use
`feature(optin_builtin_traits)`, because as the test shows, it is
only possible to impl a marker trait for a trait object in the crate the
marker trait is defined in, which must define
`feature(optin_builtin_traits)`.
Fixes#56934.

Drop partially bound function parameters in the expected order
Given the function
```rust
fn foo((_x, _): (LogDrop, LogDrop), (_, _y): (LogDrop, LogDrop)) {}
```
Prior to 1.12.0 we dropped both `_x` and `_y` before the rest of their
respective parameters, since then we dropped `_x` and `_y` after. The
original order appears to be the correct order, as the value created
later is dropped first, so we revert to that order and add a test for
it.
While this is technically a breaking change, I can't work out how
anyone could be relying on this without making their code very
brittle. If this is considered to be too likely to break real world code
then I can revert the change and change the test to check for the
current order.

Upgrade x86_64-fortanix-unknown-sgx platform support to tier 2
## Overview
1. This PR upgrades x86_64-fortanix-unknown-sgx platform support to tier 2 (std only) by setting up build automation for this target.
1. For supporting unwinding, this target needs to link to a port of LLVM's libunwind (more details could be found in #56979), which will be distributed along with the Rust binaries (similar to the extra musl objects)
### Building and copying libunwind:
We have added a new build script (`build-x86_64-fortanix-unknown-sgx-toolchain.sh`) that will run while the container is built. This will build `libunwind.a` from git source.
While the container is built, the persistent volumes where obj/ gets created aren't yet mapped. As a workaround, we copy the built `libunwind.a` to `obj/build/x86_64-unknown-linux-gnu/stage2/lib/rustlib/x86_64-fortanix-unknown-sgx/lib/` after x.py runs.
If any reviewer knows of a better solution, please do tell.
