Implement support for WebAssembly threads ... and add a parallel raytracing demo! This commit adds enough support to `wasm-bindgen` to produce a workable wasm binary *today* with the experimental WebAssembly threads support implemented in Firefox Nightly. I've tried to comment what's going on in the commits and such, but at a high level the changes made here are: * A new transformation, living in a new `wasm-bindgen-threads-xform` crate, prepares a wasm module for parallel execution. This performs a number of mundane tasks which I hope to detail in a blog post later on. * The `--no-modules` output is enhanced with more support for when shared memory is enabled, allowing passing in the module/memory to initialize the wasm instance on multiple threads (sharing both module and memory). * The `wasm-bindgen` crate now offers the ability, in `--no-modules` mode, to get a handle on the `WebAssembly.Module` instance. * The example itself requires Xargo to recompile the standard library with atomics and an experimental feature enabled. Afterwards it experimentally also enables threading support in wasm-bindgen. I've also added hopefully enough CI support to compile this example in a builder so we can upload it and poke around live online. I hope to detail more about the technical details here in a blog post soon as well!

Support for threading-related transformations in wasm-bindgen

Migrate `wasm-bindgen` to using `walrus` This commit moves `wasm-bindgen` the CLI tool from internally using `parity-wasm` for wasm parsing/serialization to instead use `walrus`. The `walrus` crate is something we've been working on recently with an aim to replace the usage of `parity-wasm` in `wasm-bindgen` to make the current CLI tool more maintainable as well as more future-proof. The `walrus` crate provides a much nicer AST to work with as well as a structured `Module`, whereas `parity-wasm` provides a very raw interface to the wasm module which isn't really appropriate for our use case. The many transformations and tweaks that wasm-bindgen does have a huge amount of ad-hoc index management to carefully craft a final wasm binary, but this is all entirely taken care for us with the `walrus` crate. Additionally, `wasm-bindgen` will ingest and rewrite the wasm file, often changing the binary offsets of functions. Eventually with DWARF debug information we'll need to be sure to preserve the debug information throughout the transformations that `wasm-bindgen` does today. This is practically impossible to do with the `parity-wasm` architecture, but `walrus` was designed from the get-go to solve this problem transparently in the `walrus` crate itself. (it doesn't today, but this is planned work) It is the intention that this does not end up regressing any `wasm-bindgen` use cases, neither in functionality or in speed. As a large change and refactoring, however, it's likely that at least something will arise! We'll want to continue to remain vigilant to any issues that come up with this commit. Note that the `gc` crate has been deleted as part of this change, as the `gc` crate is no longer necessary since `walrus` does it automatically. Additionally the `gc` crate was one of the main problems with preserving debug information as it often deletes wasm items! Finally, this also starts moving crates to the 2018 edition where necessary since `walrus` requires the 2018 edition, and in general it's more pleasant to work within the 2018 edition!

Switch from `failure` to `anyhow` (#1851) This commit switches all of `wasm-bindgen` from the `failure` crate to `anyhow`. The `anyhow` crate should serve all the purposes that we previously used `failure` for but has a few advantages: * It's based on the standard `Error` trait rather than a custom `Fail` trait, improving ecosystem compatibility. * We don't need a `#[derive(Fail)]`, which means that's less code to compile for `wasm-bindgen`. This notably helps the compile time of `web-sys` itself. * Using `Result<()>` in `fn main` with `anyhow::Error` produces human-readable output, so we can use that natively.

Rewrite wasm-bindgen with updated interface types proposal (#1882) This commit is a pretty large scale rewrite of the internals of wasm-bindgen. No user-facing changes are expected as a result of this PR, but due to the scale of changes here it's likely inevitable that at least something will break. I'm hoping to get more testing in though before landing! The purpose of this PR is to update wasm-bindgen to the current state of the interface types proposal. The wasm-bindgen tool was last updated when it was still called "WebIDL bindings" so it's been awhile! All support is now based on https://github.com/bytecodealliance/wasm-interface-types which defines parsers/binary format/writers/etc for wasm-interface types. This is a pretty massive PR and unfortunately can't really be split up any more afaik. I don't really expect realistic review of all the code here (or commits), but some high-level changes are: * Interface types now consists of a set of "adapter functions". The IR in wasm-bindgen is modeled the same way not. * Each adapter function has a list of instructions, and these instructions work at a higher level than wasm itself, for example with strings. * The wasm-bindgen tool has a suite of instructions which are specific to it and not present in the standard. (like before with webidl bindings) * The anyref/multi-value transformations are now greatly simplified. They're simply "optimization passes" over adapter functions, removing instructions that are otherwise present. This way we don't have to juggle so much all over the place, and instructions always have the same meaning.
