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.
