[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.

[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.

[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.
