Leszek Swirski authored
Avoid the linear lookup of function literal id when getting the shared function info TraceID, by optionally passing through a FunctionLiteral. Additionally, use the FunctionLiteralId helper when a FunctionLiteral is not available, since it can also fast-path in some cases. As a drive-by, allow using a ScriptIterator without an Isolate pointer (e.g. manually creating a handle) to allow calling FunctionLiteralId without an Isolate pointer.

As it stands most of ReadOnlySpace class's method are unusable once it has been sealed, since all of its pages are read-only. Set owner_ to null to ensure nothing unintentionally uses it. This also helps with separating the ReadOnlySpace from the Heap class in the future as ReadOnlySpace might not inherit from Space.

Trap handler registration happens under a spin lock, which causes lots of wasted cycles. With 48 background compilation threads, half of the wall-clock time is being spent on that spin lock. Moving this registration inside {PublishCodeLocked} avoids any lock contention (if a single module is being compiled), since we already sequentialize code publication. This speeds up background compilation for large numbers of background tasks, and has no measurable effect for small numbers.

Array push / pop / shift were inlined if the elements kind of the receiver maps is the same. This cl extends it by inlining these builtins even when the receiver maps have different elements kinds. It still limits it to only fast elements kinds. This is required to prevent regressions in deltablue when lazy feedback allocation is enabled. With lazy feedback allocation we may see polymorphic feedback more often, since we don't have allocation site feedback till the feedback vectors are allocated.

This fixes a problem where ICs for transitioning stores go MEGAMORPHIC if the transition target map dies in between invocations of the IC, which is totally possible, since we only hold on weakly to these transition targets (both from the FeedbackVectors and also from the TransitonArrays). The root problem here was an inconsistency in how the maps and handlers are being reported by the FeedbackVector. On the on hand side the method FeedbackVector::ExtractMaps() will report all receiver maps that are still present (i.e. which haven't died themselves), but then the other method FeedbackVector::FindHandlers() will only report handlers that are still alive (i.e. which in case of transition target maps being used as handlers haven't died yet). If the length of these lists don't match the IC chickens out and goes MEGAMORPHIC. But this is exactly the case with the transitioning stores, where there's no handler anymore, i.e. as can be seen in this simple example: ``` // Flags: --expose-gc function C() { this.x = 1; } new C(); new C(); gc(); // map with the `C.x` property dies new C(); // now the STORE_IC in C goes MEGAMORPHIC ``` So the problem is that we have these two methods that don't agree with each other. Now FeedbackVector::ExtractMaps() is also used by TurboFan and it even reports receiver maps for PREMONOMORPHIC state, which is different from the use case that the ICs need. So I replaced the FeedbackVector::FindHandlers() with a completely new method FeedbackVector::ExtractMapsAndHandlers(), which returns both the maps and handlers, exactly as the ICs need it. And only returns pairs for which both the receiver map and the handler are still alive. This fixes the odd problem that sometimes STORE_ICs going MEGAMORPHIC for no apparent reason. Due to the weakness of the transition target maps, they can still die and cause deoptimizations, but at least TurboFan will now be able to reoptimize again later with the new maps and still generate proper code.
