Partial no-op refactoring of #9948
This contains some prep work for #9948 to keep that change to the minimum, and make it easier to review it.
This should be a noop, but it has some tests from that PR discussion, and should help in the future with the corner case format handling.

Replace any existing `build/host` symlink
This has two advantages:
1. If `build.build` changes between runs, the symlink is no longer silently wrong.
2. If the entire build directory is moved, the symlink is no longer broken because it points to the wrong absolute path.

Improve grammar of Iterator.partition_in_place
This is my first PR against Rust, please let me know if there's anything I should be providing here! I didn't find any instructions specific to documentation grammar in the [std-dev guide](https://std-dev-guide.rust-lang.org/documentation/summary.html).
Add Nilstrieb to mailmap
I saw that I'm on https://thanks.rust-lang.org/ twice (once as `Nilstrieb` and once as `nils`).
This is because I've contributed as both `Nilstrieb` (locally) and `nils` (on github). So I've mailmapped them both to `Nilstrieb` (the less ambiguous of the two).
I am not entirely sure whether I've done this correctly.
Optimize `LazyCell` size
`LazyCell` can only store either the initializing function or the data it produces, so it does not need to reserve the space for both. Similar to #107329, but uses an `enum` instead of a `union`.

Switch to LLD as default linker for {arm,thumb}v4t-none-eabi
The LLVM 16 update brought ARMv4t support to LLD. We should use it by default so users don't need to install an external linker.
