The streaming decoder allocates the whole section buffer of the code section when it reads the section length of the code section. Therefore we have to check that the different parts of the code section actually use all the bytes, and that the different parts of the code section do not need more bytes than available. The check that all bytes are used was missing in the case where the code section contained zero functions. In addition, this CL adds some tracing to the streaming decoder which may be useful in future debugging.

Despite the V8_INLINE annotation, it was never actually inlined until 18cac20c removed the NonPatternRewriter, causing all calls to Parser::RewriteNonPattern() to inline RewriteSpreads. This patch should recover the binary bloat in the attached bug while retaining the inlining of the rest of RewriteNonPattern, which in the common case does very little work (and doesn't call out to RewriteSpreads).

Previously, the Parser stored a Scope alongside a RewritableExpression for each potential destructuring assignment. This Scope was later used during rewriting to set the correct context for the rewriting. But this approach failed if a new Scope was inserted into the Scope chain between the time the assignment was parsed and when it was rewritten. By storing the Scope directly in RewritableExpression, ReparentExpressionScopes() is able to appropriately re-scope such expressions prior to their rewriting.

At the moment, task runners are returned as unique_ptr. This is inconvenient, however. In all implementations I did, the platform holds a shared pointer of the task runner and wraps it in a wrapper class just to return it as a unique_ptr. With this CL the platform API is changed to return a shared_ptr directly.

This CL implements the TaskRunners in the DefaultPlatform which has been added recently to the platform API. In addition I changed how task posting works on the DefaultPlatform. With this implementation the DefaultPlatform keeps one DefaultForegroundTaskRunner per isolate, plus one DefaultBackgroundTaskRunner. The DefaultPlatform owns these TaskRunners with a shared_ptr, which is also shared with any caller of GetForegroundTaskRunner or GetBackgroundTaskrunner. This CL moves the task management from the DefaultPlatform to the TaskRunners. The DefaultForegroundTaskRunner owns and manages the the task queue, the delayed task queue, and the idle task queue. The DefaultBackgroundTaskRunner owns the WorkerThread pool and the background task queue. In addition changed many Task* to std::unique_ptr<Task> to document task ownership.

With this CL, {CreateDefaultPlatform} returns a unique_ptr to indicate that the caller owns the returned memory. We had several memory leaks where the memory of the DefaultPlatform did not get deallocated. In addition, the {TracingController} of the {DefaultPlatform} also gets received as a unique_ptr. Thereby we document that the {DefaultPlatform} takes ownership of the {TracingController}. Note that the memory of the {TracingController} was already owned by the {DefaultPlatform}, but it was not documented in the interface, and it was used incorrectly in tests.

- Remove weak-collection.js - Adds TFJ builtins for WeakSet and WeakMap constructors - Unified helpers and constructor behavior into a BaseCollectionsAssembler - Fast paths for... - unmodified constructor function - argument is a fast JS array - entries are fast JS arrays, for Map/WeakMap - no arguments passed Quick benchmarks shows significant improvements (1.12x - 5.7x!) for ALL collection constructors (weak and non-weak): https://github.com/peterwmwong/v8-perf/blob/master/weakcollection-constructor/README.md More could be done for performance. Currently we always call out to JS to add entries, if we knew the prototype was unmodified, we could call the builtins directly.
