    [wasm] Improve pimpl implementation in WasmInterpreter::Thread · 4f91cee3
    clemensh authored
    As no one will ever try to allocate a Thread directly, we can just make
    Thread a proxy of ThreadImpl by reinterpret_casting between both types.
    This allows to not mention ThreadImpl in the header at all, and to
    define it in an anonymous namespace in the implementation, allowing for
    more optimizations.
    It also saves runtime, as no memory load is needed to forward from
    Thread to ThreadImpl, and we do not need to allocate ThreadImpl objects
    on the heap.
