The number of worker threads in the default platform is currently capped at 8. At runtime, it's also capped by the number of actual cores available. Since d8 is often used for benchmarking (both internally and externally), this CL slightly increases the maximum to 16. At least wasm compilation is known to scale beyond 8 threads. If this increase does not cause any problems on bots, we might increase further in the future.

The serializer currently cannot handle a heap state containing arbitrary compiled Code objects. As a quick fix for the --stress-snapshot d8 flag, we clear compiled data from the isolate prior to the serialize-deserialize-verify pass. With this change, mjsunit tests pass on x64. The %SerializeDeserializeNow() runtime function would require more work, since it is not possible to mutate the heap to this extent while still preserving a runnable host context and isolate. We will need another solution there. Drive-by: Skip the stress_snapshot variant except for the mjsunit suite.

The isolate snapshot must not contain context-dependent objects, thus root visitation must not reach context-dependent objects. This CL sanitizes the isolate around serialization by clearing & later restoring two lists: 1. feedback vectors for profiling tools, 2. detached contexts. Drive-by: Set an array buffer allocator for SerializeDeserializeAndVerify. Drive-by: Allow serialization of *another* native context when serializing a native context.

Work towards adding heap-allocated object support for wasm, according to the gc proposal. Changes: - Implement subtyping for reference types (ref s) and (optref s), where 's' is a struct type. This CL does *not* implement subtyping between struct and function types. Also, it does not handle i31refs and eqrefs. - Implement struct.set. - Change struct.get to accept an optref as argument, as required by the standard. - Allow locals to store objects of ref and optref types. - Add a test for struct.set and optref locals. Modify the test for struct.get accordingly.

This removes the interpreter entry stubs, which are used to redirect specific wasm functions to the interpreter. It is only needed when mixing JS code with interpreted Wasm code, otherwise the test functions just call the interpreter directly. Thus a lot of tests that contain such interaction between JS and Wasm need to be restricted to execute in Liftoff and TurboFan only. After this CL, the WASM_INTERPRETER_ENTRY frame type and the corresponding WasmInterpreterEntryFrame are dead, and will be removed in a follow-up CL.
