All existing usages are changed to Factory::NewFixedArray(). The motivation for the removal is that the function is unsafe and easy to misuse. Note that NewUninitializedFixedArray has been already changed to initialize the result as an experiment with 3%-13% regression on a few SixSpeed microbenchmarks and no impact on larger benchmarks.

During background compilation, we check SharedFunctionInfo::HasBreakInfo() to see if the function has breakpoints for debugging, generally deciding not to inline the function if so. We were concerned about the status of this bit changing on the main thread. Happily, the main thread deoptimizes all functions that inline the given function, and shuts down all background compilation jobs as well. So it is not a meaningful concern (that of say, ignored breakpoints). Updated a comment to record this finding.

This is a reland of fd16e67e. https://chromium-review.googlesource.com/c/v8/v8/+/2843813 Reason for reland: The reland was reverted due to TSAN no-cm flakily failing due to races with the ProtectorCells[1]. The protector cells part of the method was removed in a refactor[2]. Therefore, we can re-reland with minor rebase changes in heap-refs.cc (heap.cc remains the same).

Instead of running a second pass of the scheduled graph after effect control linearization to do machine lowering, integrate the machine lowering reducers (MemoryLowering and SelectLowering) into the graph assembler used by the effect control linearization. This saves running through the graph and re-maintaining the schedule for the second time, reducing overhead in Turboprop.

We were inconsistent in handling offsets >= 2GB on 32-bit systems. The code was still relying on this being detected as statically out of bounds, but with the increase of {kV8MaxWasmMemoryPages} to support 4GB memories, this is not the case any more. This CL fixes this by again detecting such situations as statically OOB. We do not expect to be able to allocate memories of size >2GB on such systems. If this assumptions turns out to be wrong, we will erroneously trap. If that happens, we will have to explicitly disallow memories of such size on 32-bit systems.

Prior to this CL, Refs were defined through four lists: HEAP_BROKER_SERIALIZED_OBJECT_LIST HEAP_BROKER_POSSIBLY_BACKGROUND_SERIALIZED_OBJECT_LIST HEAP_BROKER_BACKGROUND_SERIALIZED_OBJECT_LIST HEAP_BROKER_NEVER_SERIALIZED_OBJECT_LIST Due to the way FooData objects are constructed (a long if-else chain generated from these lists), the order of entries within the lists and also between lists was important. In particular, subtypes had to appear before all their supertypes. Within one list this was doable, but with the split into 4 different lists this invariant cannot hold in practice. This CL refactors the four lists back into a single list to make observing the invariant possible with upcoming changes. The new unified list contains the RefSerializationKind as a second argument. Related changes are not very interesting, except for TryGetOrCreateData which now uses a set of templated functor objects for setup (this was necessary to handle different FooData constructor signatures).

Prior to this patch, `new RegExp('a/b')` logs the following in the DevTools Console: /a/b/ This is syntactically invalid. This patch fixes this while simplifying regular expression printing in general by leveraging `RegExp#toString`, instead of duplicating the logic on the inspector side. This is possible thanks to the recent work on making `RegExp#toString` more robust (v8:1982).
