Test should be educative, added english translation and pronounciation.

Constify the following methods of `core::cmp::Ordering`:
 - `reverse`
 - `then`

Stabilizes these methods as const under the `const_ordering` feature.
Also adds a test for these methods in a const context.

Possible because of rust-lang#49146 (Allow `if` and `match` in constants).

Part of rust-lang#76268

Fixes rust-lang#73268

When a deref coercion occurs, we may end up with a move error if the
base value has been partially moved out of. However, we do not indicate
anywhere that a deref coercion is occuring, resulting in an error
message with a confusing span.

This PR adds an explicit note to move errors when a deref coercion is
involved. We mention the name of the type that the deref-coercion
resolved to, as well as the `Deref::Target` associated type being used.

Thanks to marcusklaas' hard work in pulldown-cmark/pulldown-cmark#469, this fixes a lot of rustdoc bugs!

- Get rid of unnecessary `RefCell`
- Fix duplicate warnings for broken implicit reference link
- Remove unnecessary copy of links

This shows the span of the _whole_ link, including the brackets.
But rustdoc only wants to warn about the link text.

deny(unsafe_op_in_unsafe_fn) in libstd/process.rs

The libstd/process.rs part of rust-lang#73904 . Wraps the two calls to an unsafe fn Initializer::nop() in an unsafe block.

Will have to wait for rust-lang#73909 to be merged, because of the feature in the libstd/lib.rs

Consolidate some duplicate code in the sys modules.

This consolidates some modules which were duplicated throughout the sys module. The intent is to make it easier to update and maintain this code. This mainly affects the wasi, sgx, and "unsupported" targets.

I explicitly skipped hermit, cloudabi, and vxworks. These tier-3 targets have copied large sections of the sys tree. I don't think they should have, but I don't want to put effort into changing them. It also doesn't help that there aren't any scripts or instructions for building them.

There are still sections of duplicate code here and there, but this PR covers the easy parts where entire modules are the same.

Use translated variable for test string

Test should be educative, added english translation and pronounciation.

Test that bounds checks are elided for [..index] after .position()

Closes rust-lang#73396.

This was fixed by the LLVM 11 update in rust-lang#73526.

Initial support for riscv32gc_unknown_linux_gnu

Now that RISC-V 32-bit (RV32) support is in upstream glibc let's add support for userspace Rust.

Make some Ordering methods const

Resubmission of [PR#75463](rust-lang#75463) as per [PR#76172](rust-lang#76172).

Constify the following methods of `core::cmp::Ordering`:
 - `reverse`
 - `then`

Insta-stabilizes these methods as const under the `const_ordering` feature, as their implementation is a trivial match and the recent stabilization of rust-lang#49146 (Allow `if` and `match` in constants).
Note: the `const_ordering` feature has never actually been used as these methods have not been `#[rustc_const_unstable]`.

Tracking issue:  rust-lang#76113

r? @euclio

I'm not sure if the switch away from `locate` fixes any open bugs - euclio mentioned some in pulldown-cmark/pulldown-cmark#165, but I didn't see any related issues open for rustdoc. Let me know if I missed one.
