Alex Crichton 41ba851a95 Bump versions of wasm-tools crates (#4380 )

* Bump versions of wasm-tools crates

Note that this leaves new features in the component model, outer type
aliases for core wasm types, unimplemented for now.

* Move to crates.io-based versions of tools

wasm-spec-interpreter

This project shows how to use ocaml-interop to call into the Wasm spec interpreter. There are several steps to making this work:

building the OCaml Wasm spec interpreter as a static library
building a Rust-to-OCaml FFI bridge using ocaml-interop and a custom OCaml wrapper
linking both things into a Rust crate

Dependencies

This crate only builds in an environment with:

make (the Wasm spec interpreter uses a Makefile)
ocamlopt, ocamlbuild (available with, e.g., dnf install ocaml)
Linux tools (e.g. ar); currently it is easiest to build the static libraries in a single environment but this could be fixed in the future (TODO)
libgmp, for the OCaml zarith package
git is used by build.rs to retrieve the repository containing the Wasm spec interpreter; it is safe to completely remove ocaml/spec to get a new copy

Build

cargo build --features build-libinterpret

Use FFI_LIB_DIR=path/to/lib/... to specify a different location for the static library (this is mainly for debugging). If the build-libinterpret feature is not provided, this crate will build successfully but fail at runtime.

Test

cargo test --features build-libinterpret
