This way, each lazy function needs to handle only the data relevant to itself. This reduced data handling overheads. Other changes: 1) Don't deserialize the data; once it's on the heap, it can stay there. Lazy function compilation is only done in the main thread. 2) Separate ProducedPreParsedScopeData and ConsumedPreParsedScopeData. It's clearer, because: - The data looks fundamentally different when we're producing it and when we're consuming it. - Cleanly separates the operations we can do in the "producing phase" and in the "consuming phase".

This CL makes foreground compilation tasks normal (i.e. not cancelable) again, because otherwise a deadlock can happen. I think the reason why the foreground tasks were cancelable was to make sure that all tasks either finish correctly or get canceled. However, since the isolate can only shut down on the main thread, this means that the foreground task should have already finished when the isolate shuts down, or it should not have started at all. I reordered the deletion of the AsyncCompileJob though to make sure that an AsyncCompileJob is removed from CompilationManager before its promise is resolved. Here is the deadlock: The JS code which is executed after a promise is resolved is executed within the task which resolves the promise. In case of async compilation this means that some JS code is executed within a CompileTask. In JS, the shutdown of the isolate can be triggered. During the shutdown of the isolate, the CancelableTaskManager waits for all registered cancelable tasks to complete, including the CompileTask of async compilation. This means that the CancelableTaskManager waits for itself to finish, which is a deadlock.

Similar to JSCall, we can also replace uninitialized JSConstruct nodes with SOFT deopts to ensure that we don't generate unnecessary dead code. This for example shows up in the hot parts of the Node event emitter currently where the generic code for handling events with 4 or more parameters might not have been run, but we still generate most of the code because the new Array call in the beginning is not turned into a SOFT deopt immediately. Drive-by-fix: Also refactor the BytecodeGraphBuilder's handling of Construct bytecodes a bit to reduce the amount of code duplication.

Extend the use list check for the arguments object/rest parameters during apply/spread optimization to allow for more cases, such that even in code like function foo() { if (arguments.length === 1) return arguments[0]; return bar.apply(this, arguments); } we don't need to materialize the arguments object. This obviously comes with a phase ordering problem, which we resolve by introducing a waitlist in the JSCallReducer, which contains the nodes that we should check again after all the other reductions are done, and which might then be reducible. This is not 100% ideal, but get's us closer to where we want to be, and it's crucial to speed up Node core, especially the event emitter.

This CL replaces usages of utils.InstallFunctions and utils.InstallGetter() with the DEFINE_METHOD* macros that ensure that the native function is created in proper form from the beginning. Thus the function will not require further reconfiguring like adding a computed name or removing of 'prototype' property.

When internalization of the key fails because the string does not exist in the StringTable yet, then no regular object can possibly have a property with that name, so just returning "false" is safe. However, for objects with interceptors this is not true, as there may well be intercepted properties whose keys have not been internalized. So "special API objects" must take the slow path to query any interceptors.

In our internal code, we should only use pending exceptions. They will be converted to scheduled exceptions on the API boundary. Hence, the ErrorThrower just sets a pending exception; it should never have to think about scheduled exceptions. The new ScheduledErrorThrower inherits from ErrorThrower and reschedules any pending exceptions in its destructor (turning them into scheduled exceptions). In some situations, there might already be a scheduled exception, e.g. when calling other API methods (v8::Value::Get). In this case, the ErrorThrower should also not set another pending exception. For the reasons mentioned above, this can only be handled in the ScheduledErrorThrower, which is used the API methods. This fixes one DCHECK failure and one TODO about scheduled exceptions if no instance can be created, because the start function throws.
