    [inspector] Make `ArrayBuffer.[[ArrayBufferData]]` deterministic. · 833b3c96
    Benedikt Meurer authored
    Previously the internal `[[ArrayBufferData]]` property for `ArrayBuffer`
    objects reported by the inspector (and used by the DevTools front-end to
    identify `ArrayBuffer`s and `WebAssembly.Memory`s using the same backing
    store) simply contained a hex string representation of the backing store
    pointer. However that unnecessarily leaks internal addresses and more
    importantly is not deterministic, which complicates tests (just blew up
    on layout tests).
    
    This CL introduces an automatically incremented `BackingStore::id()`,
    which is used instead now and is deterministic.
