This commit goes through the dependencies that wasmtime has and updates versions where possible. This notably brings in a wasmparser/wast update which has some simd spec changes with new instructions. Otherwise most of these are just routine updates.
This crate performs the translation from a wasm module in binary format to the in-memory form of the Cranelift IR.
If you're looking for a complete WebAssembly implementation that uses this library, see Wasmtime.
