The array tests from the spec repo -- https://github.com/WebAssembly/gc/blob/main/test/core/gc/array.wast -- have not been implemented yet, since most of the tests depend on features that are not implemented yet. Once those features are implemented, the tests should be imported. I'll add the bugs that are blocking the spec tests from passing as dependencies.

I believe all these tests have been imported now & we can close
