[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%**.

[turbofan] Significantly improve ConsString creation performance. This change significantly improves the performance of string concatenation in optimized code for the case where the resulting string is represented as a ConsString. On the relevant test cases we go from serializeNaive: 10762 ms. serializeClever: 7813 ms. serializeConcat: 10271 ms. to serializeNaive: 10278 ms. serializeClever: 5533 ms. serializeConcat: 10310 ms. which represents a 30% improvement on the "clever" benchmark, which tests specifically the ConsString creation performance. This was accomplished via a couple of different steps, which are briefly outlined here: 1. The empty_string gets its own map, so that we can easily recognize and handle it appropriately in the TurboFan type system. This allows us to express (and assert) that the inputs to NewConsString are non-empty strings, making sure that TurboFan no longer creates "crippled ConsStrings" with empty left or right hand sides. 2. Further split the existing String types in TurboFan to be able to distinguish between OneByte and TwoByte strings on the type system level. This allows us to avoid having to dynamically lookup the resulting ConsString map in case of ConsString creation (i.e. when we know that both input strings are OneByte strings or at least one of the input strings is TwoByte). 3. We also introduced more finegrained feedback for the Add bytecode in the interpreter, having it collect feedback about ConsStrings, specifically ConsOneByteString and ConsTwoByteString. This feedback can be used by TurboFan to only inline the relevant code for what was seen so far. This allows us to remove the Octane/Splay specific magic in JSTypedLowering to detect ConsString creation, and instead purely rely on the feedback of what was seen so far (also making it possible to change the semantics of NewConsString to be a low-level operator, which is only introduced in SimplifiedLowering by looking at the input types of StringConcat). 4. On top of the before mentioned type and interpreter changes we added new operators CheckNonEmptyString, CheckNonEmptyOneByteString, and CheckNonEmptyTwoByteString, which perform the appropriate (dynamic) checks. There are several more improvements that are possible based on this, but since the change was already quite big, we decided not to put everything into the first change, but do some follow up tweaks to the type system, and builtin optimizations later.

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.

[es2015] Refactor the JSArrayIterator. This changes the JSArrayIterator to always have only a single instance type, instead of the zoo of instance types that we had before, and which became less useful with the specification update to when "next" is loaded from the iterator now. This greatly simplifies the baseline implementation of the array iterator, which now only looks at the iterated object during %ArrayIteratorPrototype%.next invocations. In TurboFan we introduce a new JSCreateArrayIterator operator, that holds the IterationKind and get's the iterated object as input. When optimizing %ArrayIteratorPrototype%.next in the JSCallReducer, we check whether the receiver is a JSCreateArrayIterator, and if so, we try to infer maps for the iterated object from there. If we find any, we speculatively assume that these won't have changed during iteration (as we did before with the previous approach), and generate fast code for both JSArray and JSTypedArray iteration. Drive-by-fix: Drop the fast_array_iteration protector, it's not necessary anymore since we have the deoptimization guard bit in the JSCallReducer now. This addresses the performance cliff noticed in webpack 4. The minimal repro on the tracking bug goes from console.timeEnd: mono, 124.773000 console.timeEnd: poly, 670.353000 to console.timeEnd: mono, 118.709000 console.timeEnd: poly, 141.393000 so that's a 4.7x improvement. Also make presubmit happy by adding the missing #undef's.

[async] Introduce dedicated JSAsyncFunctionObject. This JSAsyncFunctionObject represents the implicit generator object inside of async functions, and also holds the outer promise for the async functions. This in turn allows us to get rid of the .promise in the Parser / BytecodeGenerator completely, and will make it possible to build zero-cost async stack traces independent of the concrete synchronous part of the stack frame (which currently breaks in Node.js). In the bytecode all the async function operations now take this new JSAsyncFunctionObject instead of passing both the .generator_object and the .promise, which further simplifies and shrinks the bytecode. It also reduces the size of async function frames, potentially making the suspend/resume cheaper. This also changes `await` to use intrinsics instead of calling to special JSFunctions on the native context, and thus reduces the size of the native contexts. Drive-by-fix: Introduce a dedicated JSCreateAsyncFunctionObject operator to TurboFan.

[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.
