This reverts commit 6ec90ece. Reason for revert: causes a lot of Canary crashes (chromium:895208). GC relies on an the fact that the transition array stays alive while it's owner map is alive (this is needed in order to properly transfer descriptor array ownership to the parent map when the map owning a shared descriptor array dies). We need to rethink a way of caching the migration target shortcut.

During map updating, store the pointer to new map in the raw_transitions slot of the old map that is deprecated from map transition tree. Thus, we can get the migration target directly instead of TryReplayPropertyTransitions when updating map. This can improve Speedometer2.0 Elm-TodoMVC case by ~5% on ATOM Chromebook and ~9% on big-core Ubuntu.

With ReadOnlyRoots and GetIsolate on JSReceiver, we can remove almost every isolate parameter from <Object>::Print. The remaining ones, like Map, are special-caseable for read-only maps, and as a result we can remove isolate parameters from <Object>::Print entirely. This patch also opportunistically cleans up a few places where isolates were only needed for Object::Print, such as TransitionAccessors and DescriptorArrays.

Removes all explicit calls to GetIsolate() in transitions.cc by passing it through calling functions and implicit calls via the single argument Handle constructor and handle function. Unfortunately in the interests of making these changes vaguely manageable, I've also pushed some new GetIsolates down into objects-debug.cc, objects-printer.cc and objects.cc.

This pattern seems to reoccur in the code: Handle<TransitionArray> array = TransitionArray::Allocate(...); <something that causes allocation> // Fill up the array array->set(...); If the allocation causes GC, we try to iterate the TransitionArrray in MarkCompactCollector::ClearFullMapTransitions, and that crashes because it expects the TransitionArray to contain handlers (not undefined). This bug is present e.g., in TransitionAccessor::EnsureHasFullTransition.

Drive-by cleanup: remove megamorphic stub cache lookup support from generic property store code. This lookup is no longer necessary because 1) fast stores to existing properties get all the information from the map, 2) transitioning store targets are taken directly from the transition array, so in both cases there's no point in doing a store handler lookup.

Currently transition array targets have conditional weakness depending on the type of the target. Map targets are weak and all other targets are strong. This patch wraps maps in transitions arrays in weak cells, which allows us to treat all elements of transition arrays strongly. Conditional weakness is unsafe for concurrent marking because the condition can change during marking.

in preparation for caching StoreIC-Transition handlers in there. This CL should not change behavior or performance. The TransitionArray class no longer serves a dual purpose; it is now simply the data structure serving that role. Further, it now supports storing transitioning handlers in its "target" slot, which in turn have a WeakCell pointing to the transition target (but this functionality is not being used yet). The interface for accessing a map's transitions, previously implemented as a set of static functions, is now handled by the TransitionsAccessor class. It distinguishes the following internal states: - kPrototypeInfo: map is a prototype map, will never cache any transitions. - kUninitialized: map can cache transitions, but doesn't have any. - kWeakCell: map caches a single transition, stored inline. Formerly known as "IsSimpleTransition". - kFullTransitionArray: map uses a TransitionArray to store transitions. - kTuple3Handler, kFixedArrayHandler: to be used in the future for caching transitioning handlers.
