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! 2018-10-04 20:00:23 -07:00			`[package]`

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! 2019-01-31 09:54:23 -08:00			`edition = "2018"`
