Currently `Func::new` will panic if one of the arguments of the function is a reference type and the `Store` doesn't have reference types enabled. This happens because cranelift isn't configure to enable stack maps but the register allocators expects them to exist when reference types are seen. The fix here is to always enable reference types in cranelift for our trampoline generation and `Func::new`. This should hopefully ensure that trampolines are generated correctly and they'll just not be able to get hooked up to an `Instance` because validation will prevent reference types from being used elsewhere.
Wasmtime Embedding API
The wasmtime crate is an embedding API of the wasmtime WebAssembly runtime.
This is intended to be used in Rust projects and provides a high-level API of
working with WebAssembly modules.
If you're interested in embedding wasmtime in other languages, you may wish to
take a look a the C embedding API instead!
