Thanks for working on this. Since I believe the test case will assert without the added options, I'm thinking it is probably best to simply always do this in a debug compiler. Can we force enable enable-import-metadata when cloning is enabled in the thin link (or pass down a flag to ComputeCrossModuleImport to enable it)? The checking that fails without this patch should probably also go under an `#ifndef NDEBUG` (looks like I missed adding that).
