std: Add a new wasm32-unknown-unknown target This commit adds a new target to the compiler: wasm32-unknown-unknown. This target is a reimagining of what it looks like to generate WebAssembly code from Rust. Instead of using Emscripten which can bring with it a weighty runtime this instead is a target which uses only the LLVM backend for WebAssembly and a "custom linker" for now which will hopefully one day be direct calls to lld. Notable features of this target include: * There is zero runtime footprint. The target assumes nothing exists other than the wasm32 instruction set. * There is zero toolchain footprint beyond adding the target. No custom linker is needed, rustc contains everything. * Very small wasm modules can be generated directly from Rust code using this target. * Most of the standard library is stubbed out to return an error, but anything related to allocation works (aka `HashMap`, `Vec`, etc). * Naturally, any `#[no_std]` crate should be 100% compatible with this new target. This target is currently somewhat janky due to how linking works. The "linking" is currently unconditional whole program LTO (aka LLVM is being used as a linker). Naturally that means compiling programs is pretty slow! Eventually though this target should have a linker. This target is also intended to be quite experimental. I'm hoping that this can act as a catalyst for further experimentation in Rust with WebAssembly. Breaking changes are very likely to land to this target, so it's not recommended to rely on it in any critical capacity yet. We'll let you know when it's "production ready". --- Currently testing-wise this target is looking pretty good but isn't complete. I've got almost the entire `run-pass` test suite working with this target (lots of tests ignored, but many passing as well). The `core` test suite is still getting LLVM bugs fixed to get that working and will take some time. Relatively simple programs all seem to work though! --- It's worth nothing that you may not immediately see the "smallest possible wasm module" for the input you feed to rustc. For various reasons it's very difficult to get rid of the final "bloat" in vanilla rustc (again, a real linker should fix all this). For now what you'll have to do is: cargo install --git https://github.com/alexcrichton/wasm-gc wasm-gc foo.wasm bar.wasm And then `bar.wasm` should be the smallest we can get it! --- In any case for now I'd love feedback on this, particularly on the various integration points if you've got better ideas of how to approach them!

rustc: Split Emscripten to a separate codegen backend This commit introduces a separately compiled backend for Emscripten, avoiding compiling the `JSBackend` target in the main LLVM codegen backend. This builds on the foundation provided by #47671 to create a new codegen backend dedicated solely to Emscripten, removing the `JSBackend` of the main codegen backend in the process. A new field was added to each target for this commit which specifies the backend to use for translation, the default being `llvm` which is the main backend that we use. The Emscripten targets specify an `emscripten` backend instead of the main `llvm` one. There's a whole bunch of consequences of this change, but I'll try to enumerate them here: * A *second* LLVM submodule was added in this commit. The main LLVM submodule will soon start to drift from the Emscripten submodule, but currently they're both at the same revision. * Logic was added to rustbuild to *not* build the Emscripten backend by default. This is gated behind a `--enable-emscripten` flag to the configure script. By default users should neither check out the emscripten submodule nor compile it. * The `init_repo.sh` script was updated to fetch the Emscripten submodule from GitHub the same way we do the main LLVM submodule (a tarball fetch). * The Emscripten backend, turned off by default, is still turned on for a number of targets on CI. We'll only be shipping an Emscripten backend with Tier 1 platforms, though. All cross-compiled platforms will not be receiving an Emscripten backend yet. This commit means that when you download the `rustc` package in Rustup for Tier 1 platforms you'll be receiving two trans backends, one for Emscripten and one that's the general LLVM backend. If you never compile for Emscripten you'll never use the Emscripten backend, so we may update this one day to only download the Emscripten backend when you add the Emscripten target. For now though it's just an extra 10MB gzip'd. Closes #46819

rust: Import LLD for linking wasm objects This commit imports the LLD project from LLVM to serve as the default linker for the `wasm32-unknown-unknown` target. The `binaryen` submoule is consequently removed along with "binaryen linker" support in rustc. Moving to LLD brings with it a number of benefits for wasm code: * LLD is itself an actual linker, so there's no need to compile all wasm code with LTO any more. As a result builds should be *much* speedier as LTO is no longer forcibly enabled for all builds of the wasm target. * LLD is quickly becoming an "official solution" for linking wasm code together. This, I believe at least, is intended to be the main supported linker for native code and wasm moving forward. Picking up support early on should help ensure that we can help LLD identify bugs and otherwise prove that it works great for all our use cases! * Improvements to the wasm toolchain are currently primarily focused around LLVM and LLD (from what I can tell at least), so it's in general much better to be on this bandwagon for bugfixes and new features. * Historical "hacks" like `wasm-gc` will soon no longer be necessary, LLD will [natively implement][gc] `--gc-sections` (better than `wasm-gc`!) which means a postprocessor is no longer needed to show off Rust's "small wasm binary size". LLD is added in a pretty standard way to rustc right now. A new rustbuild target was defined for building LLD, and this is executed when a compiler's sysroot is being assembled. LLD is compiled against the LLVM that we've got in tree, which means we're currently on the `release_60` branch, but this may get upgraded in the near future! LLD is placed into rustc's sysroot in a `bin` directory. This is similar to where `gcc.exe` can be found on Windows. This directory is automatically added to `PATH` whenever rustc executes the linker, allowing us to define a `WasmLd` linker which implements the interface that `wasm-ld`, LLD's frontend, expects. Like Emscripten the LLD target is currently only enabled for Tier 1 platforms, notably OSX/Windows/Linux, and will need to be installed manually for compiling to wasm on other platforms. LLD is by default turned off in rustbuild, and requires a `config.toml` option to be enabled to turn it on. Finally the unstable `#![wasm_import_memory]` attribute was also removed as LLD has a native option for controlling this. [gc]: https://reviews.llvm.org/D42511
