There was a problem hiding this comment.
These two can use std::ckd_add
Spec tests pass the value `ref.extern n`, where `n` is some integer, into exported functions that expect to receive externrefs and receive such values back out as return values. The payload serves to distinguish externrefs so the test can assert that the correct one was returned. Parse these values in wast scripts and represent them as externalized i31refs carrying the payload. We will need a different representation eventually, since some tests explicitly expect these externrefs to not be i31refs, but this suffices to get several new tests passing. To get the memory64 version of table_grow.wast passing, additionally fix the interpreter to handle growing 64-bit tables correctly. Delete the local versions of the upstream tests that can now be run successfully.
