This adds a feature which allows one to look up an export by name without knowing what module it's in -- `lookup_global_export` on an `InstanceContents`. The main expected use for this is to support APIs where module A imports a function from module B, and module B needs to access module A's memory. B can't import it from A in the normal way, because that would create a dependency cycle. So for now, allow B to look up A's exported memory dynamically with `lookup_global_export`. In the future, with reference types and possibly host bindings, we'll be able to pass references to memory as arguments, which will obviate the need for this mechanism.
