* Fix module-linking handling of instance subtypes
When we alias the nth export of an instance, due to subtyping the nth
export may not actually be what we want. Instead we need to look at our
local type definition's nth export's name, and lookup that name off the
export.
* Update crates/wasmtime/src/instance.rs
