This is a workaround for not having escape analysis for wasm (machine-level) turbofan graphs. Additional change: Move IsFreshObject to NodeProperties.

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 a data property, meaning that the given PropertyAccessInfo has kind kDataDictionaryProtoConstant. Support for accessor properties is added in a separated CL.

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.

This reverts commit c85b7a44. This reland fixes missing serialization of objects stored in CallHandlerInfo::data by adding necessary handling of these objects in FunctionTemplateInfoRef::SerializeCallCode when running with direct heap access.

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.

The instance type is set before setting the map inside an Object. It is relaxed and not non-atomic to prevent a false positive TSAN failure (see https://chromium-review.googlesource.com/c/v8/v8/+/2682641).

Stepping code that is left on the stack will repeatedly call the WasmDebugBreak function. This has no observable effect, except for severe slowdown of execution. In the linked bug, we were executing at least another few million instructions in the same frame, so it appeared that it never finishes. This CL fixes that by replacing stepping code with non-stepping code if the WasmDebugBreak runtime function is called from stepping code but we are not stepping (any more). Adding a test for this is difficult, since this only has an effect on performance.

Popping values from an empty stack is allowed in unreachable code, but the stack height cannot be negative and stays at 0 instead.

Especially "kNoReturnCall" is confusing, because it can be read as "a call that does not return", which is not meant here. This CL renames the enum to "TailCall" with the boolean values "kTailCall" and "kNoTailCall". Uses of the enum can be simplified to boolean checks directly.
