[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%**.

[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.

[torque] improve GC visitors 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.

Reland: [wasm-gc] Implement rtt.sub Relanding without changes, revert reason was fixed by: https://chromium-review.googlesource.com/c/v8/v8/+/2272564 Originally reviewed at: https://chromium-review.googlesource.com/c/v8/v8/+/2260566 Original description: RTTs are internally represented as Maps. To store supertype information, this patch introduces a WasmTypeInfo object, which is installed on Wasm objects' Maps and points at both the off-heap type information and the parent RTT. In this patch, rtt.sub always creates a fresh RTT. The canonicalization that the proposal requires will be implemented later.

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.

[inspector][wasm] Re-add WasmValue as JSObject subclass. BREAKING CHANGE: The values of Wasm locals, stack, and globals are now represented as objects instead of holding the (primitive) values directly, and SIMD128 values are no longer represented as Uint8Arrays. The DWARF extension has been prepared for this breaking change. The new `WasmValue` comes with `type` and `value` properties that hold its contents. The motivation here is that this is a more extensible approach. In case of SIMD128, the `value` property holds the canonical string representation, which has the additional advantage that these values can be compared with `===` (and `==`). This partially reverts https://crrev.com/c/2614428, the main difference here being that WasmValue is now a proper JSObject that can be exposed on the DebugEvaluate proxy API.

Reland "[wasm-gc] Remove abstract rtts" This is a reland of b77deeca4bd65b006a3a6c7344c2bbabd4514122 Changes compared to original: Add explicit narrowing casts in tests for MSVC. Original change's description: > [wasm-gc] Remove abstract rtts > > In the latest wasm-gc spec, rtts of abstract types are no longer > allowed. Consequently, canonical rtts of concrete types always have > a depth of 0. > > Changes: > - Change the immediate argument of rtts to a type index over a heap > type. Abstract it with TypeIndexImmediate in function body decoding. > This affects: > value_type.h, read_value_type(), decoding of relevant opcodes, > wasm subtyping, WasmInitExpr, consume_init_expr(), and > wasm-module-builder.cc. > - In function-body-decoder-impl.h, update rtt.canon to always produce > an rtt of depth 0. > - Pass a unit32_t type index over a HeapType to all rtt-related > utilities. > - Remove infrastructure for abstract-type rtts from the wasm compilers, > setup-heap-internal.cc, roots.h, and module-instantiate.cc. > - Remove ObjectReferenceKnowledge::rtt_is_i31. Remove related branches > from ref.test, ref.cast and br_on_cast implementations in the wasm > compilers. > - Remove unused 'parent' field from WasmTypeInfo. > - Make the parent argument optional in NewWasmTypeInfo, CreateStructMap, > and CreateArrayMap. > - Use more convenient arguments in IsHeapSubtypeOf. > - Update tests. > > Bug: v8:7748 > Change-Id: Ib45efe0741e6558c9b291fc8b4a75ae303146bdc > Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2642248 > Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> > Reviewed-by: Ulan Degenbaev <ulan@chromium.org> > Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> > Cr-Commit-Position: refs/heads/master@{#72321} Bug: v8:7748 Change-Id: I22b204b486fd185077cd6c7f15d492f5143f48fe Reviewed-on: https://chromium-review.googlesource.com/c/v8/v8/+/2650207 Commit-Queue: Manos Koukoutos <manoskouk@chromium.org> Reviewed-by: Jakob Kummerow <jkummerow@chromium.org> Reviewed-by: Ulan Degenbaev <ulan@chromium.org> Cr-Commit-Position: refs/heads/master@{#72355}

[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.

[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.
