We've generally moved to a model where `InstanceHandle` doesn't hold ownership of its internals, instead relying on the caller to manage that. This removes an allocation on the `Func::wrap` path but otherwise shouldn't have much impact.
This is the wasmtime-jit crate, which contains JIT-based execution
for wasm, using the wasm ABI defined by wasmtime-environ and the
runtime support provided by wasmtime-runtime.
Most users will want to use the main wasmtime crate instead of using this
crate directly.
