Allow the DevTools frontend to evaluate variables in a wasm frame context by reusing the existing Debugger expression evaluation API. Where previously the API expected JavaScript expressions, which would in general just fail, now the expression is expected to be base64 encoded Wasm that creates a JSON string in linear memory.

The flag is used by V8 to propagate information on whether this GC was somehow forced. This allows the embedder using EmbedderHeapTracer to easily figure out whether a GC was forced based on a local flag without depending on GC prologue/epilogue callbacks.

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.

On intel platforms, floats do not always have a stable bit pattern. To preserve the bit pattern of float immediates, we should keep them in an int using get_bits() instead of casting them to a float with get_scalar().

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.

Summary of changes: - GC visitors no longer rely on superclass visitors, but instead visit everything themselves. This enables generating better code. - Try to match simple body descriptors to reduce the amount of generated code. - Turn SizeFor(instance) into an AllocatedSize() method. - Remove the special handling of resizable object sizes from Torque and instead overwrite AllocatedSize in classes that need special handling in C++. - Split the visitor id lists depending on whether the class has pointer fields. - Turn Torque-generated body descriptors into an .inc file to simplify includes. - Fix generated size functions to properly align the size. - Generate GC visitors (and C++ class definitions) for all string classes and FixedArray, WeakFixedArray, and WeakArrayList. - Store generated instance types in Torque class types. This is only used to determine if a type has a single instance type in this CL.
