Update rust-toolchain and emscripten-toolchain to LLVM 12

lopopolo · lopopolo · commit c67a20a32990 · 2021-08-05T06:54:53.000-07:00
Artichoke only compiles with Rust 1.54.0. Rust 1.54.0 is based on LLVM 12 (rust-lang/rust#81451). To ensure the `emcc` compiled sources interop with Rust code, it is important to use an `emsdk` version that is ~close to when it was branched from LLVM 12. According to the release notes [0], 2.0.23 - 05/26/2021 release is the first to be based on LLVM 12. However, Rust depends on a stubbed function in the emsdk c++ ABI that was removed in 2.0.10. According to rust-lang/rust#85821, we might have luck compiling with 2.0.9 [0]: https://emscripten.org/docs/introducing_emscripten/release_notes.html emscripten-toolchain
