With the arrival of generic structs (https://chromium-review.googlesource.com/c/v8/v8/+/1714868) the existing type inference procedure for generic calls became incomplete, since it could not infer types that were only constrained as part of generic types. For instance, given struct Box<T: Type> { ... } macro unbox<T: type>(box: Box<T>): T the type argument (Smi) at the following call site const box: Box<Smi> = ...; unbox(box); could not be inferred. This CL re-implements the inference procedure and documents the semantics of type argument inference in Torque a bit more clearly.

On Windows ARM64, OS stack walking does not work because the V8 ARM64 backend doesn't emit unwinding info and also because it doesn't emit ABI compliant stack frames. This was fixed for Windows X64 (https://crrev.com/c/1469329) and documented below: https://docs.google.com/document/d/1-wf50jFlii0c_Pr52lm2ZU-49m220nhYMrHDi3vXnh0 This problem can be fixed similarly for Windows ARM64 by observing that V8 frames usually all have the same prolog which maintains a chain via frame pointer (fp or x29 register). stp fp, lr, [sp, ...] One exception is JSEntry which stops fp pointer chain and needs to be handled specially. So it is possible to define XDATA with UNWIND_CODE which specify how Windows should walk through V8 dynamic frames. The same as X64, since V8 Code objects are all allocated in the same code-range for an Isolate, it is possible to register at most 2 XDATA and a group of PDATA entries to cover stack walking for all the code generated inside that code-range. This is more than 1 PDATA/XDATA because according to the Windows ARM64 exeption handling document, 1 PDATA can cover less than 1MB code range (see below doc). https://docs.microsoft.com/en-us/cpp/build/arm64-exception-handling This PR implements stackwalk for Windows ARM64 to be on par with X64, including embedded builtins, jitted code and wasm jitted code, but not including register handler for handling exception only, because there is no backward compatibility to maintain for Windows ARM64 which was released since 1709 windows build.

Do not pass the deoptimization index in a register, instead infer it from the address we made the deoptimization call from. This makes the deoptimization exit sequence one instruction long instead of two. This requires emitting all deoptimization exits at the end of the function in a contiguous block, making sure no constant or veneer pools are emitted in between. This means that soft deoptimizations require an additional branch to the end of the function, which counteracts the removal of the move instruction, however soft deoptimizations are rare compared to eager and lazy ones. This reduces the code size of optimised functions for benchmarks like Octane and ARES-6 by about 4%.

This patch adds: - VariableMode::kPrivateMethod - VariableMode::kPrivateSetterOnly - VariableMode::kPrivateGetterOnly - VariableMode::kPrivateGetterAndSetter And replace the previous RequiresBrandCheckFlag by inferring whether the brand check is required from these VariableModes. It is then possible to check duplicate non-complementary accessors in the parsers and throw early errors, and allow complementary accessors to be associated with the same private name variable. This patch also adds the following AssignType: - PRIVATE_METHOD - PRIVATE_GETTER_ONLY - PRIVATE_SETTER_ONLY - PRIVATE_GETTER_AND_SETTER corresponding to the new VariableModes so that it's possible to generate specialized code for different type of private accessor declarations.

On Windows, the FP stack registers are used with less precision. This causes rounding errors in the uint64 to float32 conversion. This CL replaces the implementation based on FP stack registers with an implementation based on bit operations. This implementation is 2x slower than the original implementation. An alternative would be to change the precision of the FP stack registers just for the uint64 to float32 conversion. However, in a micro-benchmark this is 5-6x slower than the original implementation. It is also not clear if changing the precision could cause side effects.

Previously, this was run as a microtask and this CL changes it to run as a separate task as mandated by the current WeakRef spec. This CL also introduces a FinalizationGroup type to the V8 API representing the JSFinalizationGroup. This has a `Cleanup` function that runs the cleanup callback associated with it. SetHostCleanupFinalizationGroupCallback is added to set the embedder defined HostCleanupFinalizationGroupCallback. ClearKeptObject is exposed on the v8::Isolate to reset the strongly held set of objects. The general workflow is the following: (a) When the GC notices that a given finalization group has dirty cells, it calls HostCleanupFinalizationGroupCallback with the given finalization group. (b) As part of HostCleanupFinalizationGroupCallback, the embedder enqueues a task that at some point later calls FinalizationGroup::Cleanup. (c) At some point in the future, FinalizationGroup::Cleanup is called, which runs the cleanup callback of the finalization group. This patch also includes d8 changes to use these new APIs. Currently, d8 cycles through the enqueued finalization groups after a synchronous turn (and it's microtask checkpoint) and runs the cleanup callbacks.

Currently, each single CSA_ASSERT invokation creates its own lambda, which is then wrapped in a {std::function} and passed to {CodeStubAssembler::Assert}. It takes a lot of compile time for clang to generate all the code for that. This CL introduces a more light-weight alternative to {CodeStubAssembler::Assert} which just receives the node directly. This reduces compile time of {code-stub-assembler.cc} in optdebug mode from ~30 seconds to ~17 seconds locally.
