Note: I noticed this uses `LangASMap`, but doesn't specify a value for `wasm_funcref`, which will invisibly initialize it to `0` (initializer shorter than array type `LangASMap`) and that maps to the dummy value of `FLAT_ADDRESS` likely desired anyway.  It doesn't rely on this auto-initialization for sycl_global and beyond though, even though it could.
