These default to doing nothing, but implementations can override them to preallocate buffers. Also, reorder the functions in `ModuleEnvironment` to more closely reflect the sequence from the WebAssembly module layout.
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.
