Add support for wasm exception handling to Emscripten target
This is a draft because we need some additional setting for the Emscripten target to select between the old exception handling and the new exception handling. I don't know how to add a setting like that, would appreciate advice from Rust folks. We could maybe choose to use the new exception handling if `Ctarget-feature=+exception-handling` is passed? I tried this but I get errors from llvm so I'm not doing it right.
add m68k-unknown-none-elf target
r? `@workingjubilee`
The existing `m68k-unknown-linux-gnu` target builds `std` by default, requires atomics, and has a base cpu with an fpu. A smaller/more embedded target is desirable both to have a baseline target for the ISA, as well to make debugging easier for working on the llvm backend. Currently this target is using the `M68010` as the minimum CPU due, but as missing features are merged into the `M68k` llvm backend I am hoping to lower this further.
I have been able to build very small crates using a toolchain built against this target (together with a later version of `object`) using the configuration described in the target platform-support documentation, although getting anything of substantial complexity to build quickly hits errors in the llvm backend
Target: Add mips mti baremetal support
Do the same thing as gcc, which use the vendor `mti` to mark the toolchain as MIPS32r2 default.
We support both big endian and little endian flavor:
mips-mti-none-elf
mipsel-mti-none-elf
Add UWP (msvc) target support page
- Added Platform Support page for `x86_64-uwp-windows-msvc`, `i686-uwp-windows-msvc`, `thumbv7a-uwp-windows-msvc` and `aarch64-uwp-windows-msvc`
- Adding myself as a maintainer
- Removing the ticks for `thumbv7a-pc-windows-msvc` and `thumbv7a-uwp-windows-msvc` as they do not currently build due to #134565 and https://github.com/rust-lang/backtrace-rs/pull/685
- Fixed a few minor issues to let most of the UWP targets compile
- Happy new year to all!

Revert #119515 single line where clause style guide
This did not get implemented for the style edition in 2024, so this PR removes it from the documentation.
See tracking issue https://github.com/rust-lang/rust/issues/132381.
This can be added back in the next edition if it gets implemented. I'm a little unclear on what the style team intends for how future changes are documented. For example, the current style-guide documented behavior that rustfmt does not support. I'm not sure who the audience for this document is, or how this is intended to stay in sync with rustfmt. For example, if I read this and assume this is how it is supposed to work, and then rustfmt breaks that, it seems like that is confusing. Similarly, if I'm staying on an older edition, this documentation would be incorrect for my crate.
Perhaps changes like this could be "teed-up" in a PR, but not merged until the edition is stabilized (similar to how the reference works)? And include notes for parts that are edition-specific (so if I am using an older edition, I can see that something is different). In general, I'm a little confused on how this is intended to work.

Add illumos target documentation
Fixes https://github.com/rust-lang/rust/pull/130132#issuecomment-2339055221
`@jclulow` `@pfmooney` I'm adding you as requested.
The page is very barebones (as I do not know illumos well) and could use some improvements (for example in the "Cross-compilation toolchains and C code" section).
Feel free to suggest improvements (or rewrite it from scratch) if you find something.

Improve default target options for x86_64-unknown-linux-none
Without a standard library, we cannot unwind, so it should be panic=abort by default.
Additionally, it does not have std because while it is Linux, it cannot use libc, which std uses today for Linux.
Using PIE by default may be surprising to users, as shown in #134763, so I've documented it explicitly. I'm not sure if we want to count that as fixing the issue or not.
cc `@morr0ne,` as you added the target (and are the maintainer), and `@Noratrieb,` who reviewed that PR (:D).
