[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%**.

[string] Add a is_shared bit to strings and String::Share The is_shared bit bumps the number of reserved bits for Strings' InstanceType from 6 to 7. This has the side effect of shuffling the InstanceType enum values. There are no users of this bit yet. This is steps 1-2 from the following design doc [1], in preparation for sharing internalized and in-place-internalizable strings.

[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.

Check instance type before initializing embedder data slots JSObject::InitializeBody now checks whether the instance type of the object being initialized can have embedder data slots around the initialization logic for these slots. This fixes a performance regression on certain benchmarks. To perform this check efficiently, a new instance type, JSObjectWithEmbedderSlots, is introduced so that the check becomes a simple range check.

[cleanup] Fix frame mismatch for WasmToJs functions There are 2 kinds of WasmToJs code: one uses a WasmFrame and the other a simple TypedFrame TF frame. This CL introduces WasmToJsFunctionFrame (as a simple TypedFrame) to dfferentiate from the WasmFrame counterpart. This was not an issue before https://crrev.com/c9c490891ab3d63fc790770cb1c76f8013ba963f since we used to use a single master function for pointer iteration.

[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.

"TURBOFAN_STUB_WITH_CONTEXT",
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.
