If an enum case has a type annotation, the corresponding enum constant has this type. This is useful for typing context slots.

This is a JavaScript fuzzer originally authored by Oliver Chang. It is a mutation based fuzzer using Babel code transformations. For more information see the included README.md. The original code was altered: - Add new V8 copyright headers. - Make the test expectation generator aware of the headers. - Fix file endings for presubmit checks. - Fix `npm test` on fresh checkout with a new fake DB. - Make test skipping work with new v8/tools location. - OWNERS file. - New title section in README.md.

This adds new methods AllocateSharedPages, ReserveForSharedMemoryMapping and CanAllocateSharedPages to v8::PageAllocator, which if overridden allows the platform to declare that it supports allocation and remapping of shared memory. This interface is currently a work in progress so the new methods are marked "INTERNAL ONLY" and they may change without being first deprecated. An implementation of PageAllocator is provided that can allocate and map shared memory on Linux and Android, but no other platforms are yet supported. While Windows is not supported the interface has been designed to make this possible as AllocateSharedPages returns a SharedMemory object that wraps the shared memory and provides its own remap function. This should allow the SharedMemory object on windows to contain a mapping a to hFileMappingObject as required by MapViewOfFileEx.

Since we now add the additional required capacity when assessing StringTable shrinking during LookupKey-caused string insertion, we no longer have to add a slack capacity. This more closely matches previous behaviour, which didn't consider the additional required capacity but did add slack (which, because of rounding to the next power of two, amounts to the same thing).

If we don't have slack and we want to add an element to the TransitionArray, we would create a new TransitionArray. The background hread, however, can be holding a pointer to the old transitions. This test tests that this is safe to do, i.e the background thread reading the old TransitionArray. To make sure that we are testing that, we can add more synchronization via an extra semaphore.
