    [wasm] Always provide a wasm instance object at runtime · 21a85c4a
    clemensh authored
    When executing wasm code for testing, we did not create a
    WasmInstanceObject and link it to the generated code. This required
    some special handling at runtime (mainly for stack trace generation).
    This CL always provides the WasmInstanceObject, such that e.g. function
    names can be resolved the usual way.
    The module bytes referenced by the WasmCompiledModule linked with the
    WasmInstanceObject do not hold a valid wasm module yet. Instead, we
    just add the bytes we need, and make the objects in WasmModule point to
    those bytes (currently only used for function names). Those bytes will
    not be parsed at runtime anyway.
