Add capability of throwing values in WASM This is a second attempt at landing CL 644866 which was reverted by CL 667019. Extends the current implementation of WASM exceptions to be able to throw exceptions with values (not just tags). A JS typed (uint_16) array is used to hold the thrown values. This allows all WASM types to be stored (i32, i64, f32, and f64) as well as be inspected in JS. The previous CL was reverted because the WASM compiler made calls to run time functions with tagged objects, which must not be done. To fix this, all run time calls use the thread-level isolate to hold the exception being processed.

[inspector] introduced console.context console.context(name:string) method returns console instance, this console instance fully implements console interface (including fact that any method can be called without console as receiver). Protocol.Runtime.consoleAPICalled notification contains additional context:string field: - "anonymous#unique-id" for any method call on unnamed console context, - "name#unique-id" for any method call on named console context. console.count and console.timeEnd have context as a scope. console.clear clear all messages regardless on what context instance it was called. console calls is ~10% slower with this CL since we need to store and then fetch console_context_id and console_context_name from function object. We recently (in April) made console calls twice faster so 10% doesn't sound critical and existing of console.log call in hot code is problem by itself.

[class] Store class fields initializer on the constructor Previously, the class fields initializer function was stored on a synthetic context allocated variable. This approach had sevaral problems: - We didn't know that class literal had fields until after we had completely parsed the class literal. This meant that we had to go back and fix up the scope of the constructor to have this synthetic variable. This resulted in mismatch between parser and preparsed scope data. - This synthetic variable could potentially resolve to an initializer of an outer class. For ex: class X extends Object { c = 1; constructor() { var t = () => { class P extends Object { constructor() { var t = () => { super(); }; t(); } } super(); } t(); } } In this the inner class P could access the outer class X's initiliazer function. We would have to maintain extra metadata to make sure this doesn't happen. Instead this new approach uses a private symbol to store the initializer function on the class constructor itself. For the base constructor case, we can simply check for a bit on the constructor function literal to see if we need to emit code that loads and calls this initializer function. Therefore, we don't pay the cost of loading this function in case there are no class fields. For the derived constructor case, there are two possiblities: (a) We are in a super() call directly in the derived constructor: In this case we can do a check similar to the base constructor check, we can check for a bit on the derived constructor and emit code for loading and calling the initializer function. This is usually the common case and we don't pay any cost for not using class fields. (b) We are in a super() call inside an arrow function in the derived constructor: In this case, we /always/ emit code to load and call the initializer function. If the function doesn't exist then we have undefined and we don't call anything. Otherwise we call the function. super() can't be called twice so even if we emit code to load and call the initializer function multiple times, it doesn't matter because it would have already been an error.

[turbofan] Optimize O.p.hasOwnProperty inside for-in. Optimize the common pattern for (var i in o) { if (Object.prototype.hasOwnProperty.call(o, i)) { // do something } } which is part of the guard-for-in style in ESLint (see the documentation at https://eslint.org/docs/rules/guard-for-in for details). This pattern also shows up in React and Ember applications quite a lot (and is tested by the appropriate Speedometer benchmarks, although not dominating those benchmarks, since they spent a lot of time in non-TurboFan'ed code). This improves the forInHasOwnProperty and forInHasOwnPropertySafe micro- benchmarks in v8:6702, which look like this function forInHasOwnProperty(o) { var result = 0; for (var i in o) { if (o.hasOwnProperty(i)) { result += 1; } } return result; } function forInHasOwnPropertySafe(o) { var result = 0; for (var i in o) { if (Object.prototype.hasOwnProperty.call(o, i)) { result += 1; } } return result; } by around 4x and allows for additional optimizations in the future, by also elimiating the megamorphic load when accessing the enumerated properties. This changes the interpreter ForInNext bytecode to collect more precise feedback about the for-in state, which now consists of three individual states: UNINITIALIZED, MEGAMORPHIC and GENERIC. The MEGAMORPHIC state means that the ForInNext has only seen objects with a usable enum cache thus far, whereas GENERIC means that we have seen some slow-mode for..in objects as well.

Details: - Do not stop concurrent marking when entering the atomic pause. - Start concurrent marking when it was off.
