This is a reland of https://chromium-review.googlesource.com/c/v8/v8/+/2720300. As compared to the original version, it adds --no-stress-flush-bytecode to the const-dict-tracking.js test Original description: This CL is part of a series that implements Turbofan support for property accesses satisfying the following conditions: 1. The holder is a dictionary mode object. 2. The holder is a prototype. 3. The access is a load. This feature will only be enabled if the build flag v8_dict_property_const_tracking is set. This particular CL implements support for the case that the property in question is an accesor, meaning that the given PropertyAccessInfo has kind kAccessorDictionaryProtoConstant.

The most common case is still one of the unconditionally supported (MVP) types. Hence avoid the switch and the flags / CPU features lookup in the hot function, and offload that to a rarely called function. The fast path is now just a bit check via an EnumSet.

If we have baseline code, deoptimize to baseline instead of the interpreter. The process is similar to deopting to the interpreter. We just use different builtins (BaselineEnterAtBytecode/BaselineEnterAtNextBytecode) instead of InterpreterEnterBytecodeDispatch/InterpreterEnterBytecodeAdvance, that patch an interpreter frame to a baseline frame and continue execution in baseline code (based on the deopt type, at the current or next bytecode).

Calculate the maximum call size in the bytecode pre-visit, and pass that (along with the bytecode's frame size) to the prologue to be included in the stack check. This avoids doing a stack check before each call, and mirrors a similar optimisation in TurboFan. Also, use StackGuardWithGap instead of StackGuard, to make sure that stack overflows in the prologue actually trigger stack overflows in the runtime.

Origin trials allow webpages to use experimental features even though the features are not yet enabled by default. These features will then get enabled per execution context: it is possible that the feature is enabled in one execution context but disabled in another execution context. In V8 we check for origin trials by calling a callback provided by the embedder that takes the context as a parameter and returns whether a feature is enabled in this context or not. This approach fails when a feature changes the context itself, e.g. by extending the global object. In that case the context is not available yet to check for the origin trial. To solve the problem this CL adds a new API function that can be called by the embedder to notify V8 that context with the origin trial information is finished. After that V8 can read the origin trial information from the context and extend e.g. the global object with the origin trial features. Additionally to the API this CL also adds code to enable the WebAssembly.Exception constructor conditionally, depending on whether it has been enabled by an origin trial or not.

LoadImmutable represents a load from a position in memory that is known to be immutable, e.g. an immutable IsolateRoot or an immutable field of a WasmInstanceObject. Because the returned value cannot change through the execution of a function, LoadImmutable is a pure operator and does not have effect or control edges. This will allow more aggressive optimizations of loads of fields of the Isolate and Instance that are known to be immutable. Requires that the memory in question has been initialized at function start even through inlining. Note: We may reconsider this approach once we have escape analysis for wasm, and replace it with immutable load/initialize operators that live inside the effect chain and are less restriced.

When swizzle is called with a v128.const node, we can check that the indices are either all in bounds, or if they are out of bounds the top bit of each byte is set. This will match exactly pshufb behavior, and so we can omit the paddusb (and getting external reference).
