[cleanup] Remove obsolete "one byte data hint" for strings. In the early days of Chrome when we used WebKit there was no support for ASCII strings on the C++ side, so we put a hint onto these two-byte strings that said "string only contains one byte data", such that internally in V8 when these were involved in string operations, we could instead create the *cheaper* one byte strings. Nowadays Blink properly supports one-byte string representations and this additional hint only comes with overhead, since we check it in quite a few places (i.e. on the hot path for string concatenation), plus we end up consuming more memory due to the additional string maps. Removing the hint also frees one bit in the InstanceType zoo for strings. This alone improves performance on the `bench-dom-serialize.js` test case by around **3%**.

[wasm] Internal representation for function references Design doc: bit.ly/3jEVgzz We separate the internal representation of function references in Wasm from their JSFunction-based (external) representation. This improves performance of call_ref by requiring less indirections to load the context and call target from a function reference. In the boundary between wasm and JS/the C API, we add transformations between the two representations. Detailed changes: - Introduce WasmInternalFunction, containing fields required by call_ref, as well as a reference to the corresponding WasmExternalFunction. Add a reference to the WasmInternalFunction in WasmFunctionData. The {WasmInternalFunction::FromExternal} helper extracts the internal out of an external function. - Change {WasmInstanceObject::external_functions()} to internal functions. - Change wasm function tables to contain internal functions. - Change the following code to use internal functions: - call_ref in liftoff and Turbofan - function type checks in liftoff and Turbofan - CallRefIC and GenericJSToWasmWrapper builtins - {InitExprInterface::RefFunc} - module-compiler.cc in {ProcessTypeFeedback} - In module-instantiate.cc, in function-rtt creation. - Add transformations between internal and external functions in: - WasmWrapperGraphBuilder::{ToJS, BuildUnpackObjectWrapper, FromJS, BuildJSToJSWrapper}. - debug-wasm-objects.cc in {FunctionProxy::Get}, {WasmValueObject::New} and {AddWasmTableObjectInternalProperties}. - runtime-wasm.cc in ReplaceWrapper - the C and JS APIs - module-instantiate.cc, in import and export processing, as well as {InitializeIndirectFunctionTables} - WasmTableObject::{IsValidElement, SetFunctionTableEntry} - {WasmGlobalObject::SetFuncRef} - Simplify body descriptors of WasmExternalFunction variants. - Adjust tests.

This CL adds the v8::internal::StackFrameInfo class as new backing implementation of v8::StackFrame, and puts it into debug-objects.tq to indicate that it's used for the debugger API only. This new class is lightweight and only holds on to static information about the stack frame, and is thus usable for the V8 inspector to implement async stack traces in a cheaper manner going forward.

[inspector] Capture stack trace only once for JSError objects. When creating a new JSError object (or using the non-standard API `Error.captureStackTrace`) V8 would previously capture the "simple stack trace" (as FixedArray of CallSiteInfo instances) to be used for the non- standard `error.stack` property, and if the inspector was active also capture the "detailed stack trace" (as FixedArray of StackFrameInfo instances). This turns out to be quite a lot of overhead, both in terms of execution time as well as memory pressure, especially since the information needed for the inspector is a proper subset of the information needed by `error.stack`. So this CL addresses the above issue by capturing only the "simple stack trace" (in the common case) and computing the "detailed stack trace" from the "simple stack trace" when on demand. This is accomplished by introducing a new ErrorStackData container that is used to store the stack trace information on JSErrors when the inspector is active. When capturing stack trace for a JSError object while the inspector is active, we take the maximum of the program controlled stack trace limit and the inspector requested stack trace limit, and memorize the program controlled stack trace limit for later formatting (to ensure that the presence of the inspector is not observable by the program). On the `standalone.js` benchmark from crbug.com/1283162 (with the default max call stack size of 200) we reduce execution time by around 16% compared to ToT. And compared to V8 9.9.4 (the version prior to the regression in crbug.com/1280831), we are 6% faster now.

[torque] Generate instance types Design doc: https://docs.google.com/document/d/1ZU6rCvF2YHBGMLujWqqaxlPsjFfjKDE9C3-EugfdlAE/edit Changes from the design doc: - Changed to use 'class' declarations rather than 'type' declarations for things that need instance types but whose layout is not known to Torque. These declarations end with a semicolon rather than having a full set of methods and fields surrounded by {}. If the class's name should not be treated as a class name in generated output (because it's actually a template, or doesn't exist at all), we use the standard 'generates' clause to declare the most appropriate C++ class. - Removed @instanceTypeName. - @highestInstanceType became @highestInstanceTypeWithinParentClassRange to indicate a semantic change: it no longer denotes the highest instance type globally, but only within the range of values for its immediate parent class. This lets us use it for Oddball, which is expected to be the highest primitive type. - Added new abstract classes JSCustomElementsObject and JSSpecialObject to help with some range checks. - Added @lowestInstanceTypeWithinParentClassRange so we can move the new classes JSCustomElementsObject and JSSpecialObject to the beginning of the JSObject range. This seems like the least-brittle way to establish ranges that also include JSProxy (and these ranges are verified with static assertions in instance-type.h). - Renamed @instanceTypeValue to @apiExposedInstanceTypeValue. - Renamed @instanceTypeFlags to @reserveBitsInInstanceType. This change introduces the new annotations and adds the ability for Torque to assign instance types that satisfy those annotations. Torque now emits two new macros: - TORQUE_ASSIGNED_INSTANCE_TYPES, which is used to define the InstanceType enumeration - TORQUE_ASSIGNED_INSTANCE_TYPE_LIST, which replaces the non-String parts of INSTANCE_TYPE_LIST The design document mentions a couple of other macro lists that could easily be replaced, but I'd like to defer those to a subsequent checkin because this one is already pretty large.

Reduce max instance type enum value. We collect instance type statistics in FatalProcessOutOfMemory into an array, which is allocated to the max instance type value. While we want to leave space to ensure new instance types do not affect constants in the API, we can be more frugal. We currently serialize 350 maps into the startup/context snapshot. Even if we assign a distinct instance type to each of these maps, we would still have more than enough to spare with this change.

[shared-struct] Shared Array Initial prototype Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might change in the future. Shared arrays can be shared across Isolates, have a fixed size, have no prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays. The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

[heap] Remove sweeping_slot_set_ from MemoryChunk Since the new space is always empty after a full GC, the old-to-new remembered set is also always empty after a full GC. This means we can get rid of the sweeping_slot_set_. This slot set was used to allow the main thread to insert into the old-to-new remembered set non-atomically. The sweeping slot set was owned by the sweeper, which deletes slots in free memory from it. The main thread would start with an empty old-to-new remembered set. After sweeping both slot sets are merged again. The sweeper now needs to behave differently during a GC. When sweeping a page during full GC, the sweeper needs to delete old-to-new-slots in free memory. Outside of the GC the sweeper isn't allowed to remove from the old-to-new slots anymore. This would race with the main thread that adds slots to that remembered set while the sweeper is running. However, there should be no recorded slots in free memory. DCHECKing this is tricky though, because we would need to synchronize with the main thread right-trimming objects and at least String::MakeThin only deletes slots after the map release-store.

When sweeping a page during full GC, the sweeper needs to delete old-to-new-slots in free memory. Outside of the GC the sweeper isn't allowed to remove from the old-to-new slots anymore. This would race with the main thread that adds slots to that remembered set while the sweeper is running. However, there should be no recorded slots in free memory. DCHECKing this is tricky though, because we would need to synchronize with the main thread right-trimming objects and at least String::MakeThin only deletes slots after the map release-store.

[shared-struct] Shared Array Initial prototype Initial implementation for concurrent shared arrays. Current implementation exposes a `SharedArray` constructor, but its syntax might change in the future. Shared arrays can be shared across Isolates, have a fixed size, have no prototype, have no constructor, and can only store primitives, shared structs and other shared arrays. With this CL shared structs are also allowed to store shared arrays. The Backing storage for the SharedArrays is a `FixedArrayBase`. This CL introdces a new ElementKind: `SHARED_ARRAY_ELEMENTS`. The new kind should match the overall functionality of the `PACKED_SEALED_ELEMENTS` kind, but having it as standalone kind allows for easier branching in CSA and turbofan code.

[wasm] [debug] Implement calling imported wasm functions The interpreter was not able to call imported wasm functions (hitting UNIMPLEMENTED). This CL fixes this by creating a "CWasmEntry", which is signature-specific. It has JS linkage and receives the wasm code object to call and a buffer containing all arguments (similar to the interpreter entry). It loads all arguments from the buffer and calls the given code object. The c-wasm-entry code objects are cached per instance, such that we only create them once per signature. These wasm entry stubs will also allow us to call back to compiled code from the interpreter, which we might want to do to reduce the slowdown of executing wasm for debugging.

Inline Array.prototype.forEach in TurboFan This CL contains a few pieces: - A new mechanism to create "BuiltinContinuation" checkpoints in TurboFan graphs, which--when triggered--swizzle the values in the the FrameState to be parameters to a typically TF-generated builtin that resumes execution to finish the slow-case functionality. - Continuation builtins that have special handling in the deoptimizer and their own new frame type to ensure that the values they need to begin executing can be stashed away and restored immediately before the builtin is called via a trampoline that runs when the continuation builtin's frame execution resumes. - An implementation of Array.prototype.forEach in TurboFan that can be used to inline it. The inlined forEach implementation uses the checkpoints mechanism described above to deopt in the middle of the forEach in the cases that optimization invariants are violated. There is a slightly different continuation stub for each deopt point in the forEach implementation to ensure the correct side-effects, i.e. that the deopt of the builtin isn't programmatically observable.

[promises/deoptimizer] Support "catching" builtin continuations This CL allows builtin continuations to handle pending exceptions. This implements exception handling for the promise constructor in case of deoptimization.

[cpu-profiler] Introduce NativeFrame type. The new frame type is inteneded to represent native C++ stack frames. JS code may sometimes make calls to helper native functions that do not provide any special stack layout besides the return address and frame pointer. Currently the stack iterator bails out when it sees an unknown frame. The patch allows the iterator to unwind stacks having such frames.
