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.

Registers used for Phis are marked specially between the point where the Phi is defined, and the gap-move's in the predecessor blocks which populate the Phi value, since if the Phi is spilled then all predecessor blocks must also spill the Phi even if they were already allocated.

PersistentHandlesScope works similar to the DeferredHandleScope, but returns PersistentHandles instead of DeferredHandles on Detach(). Since PersistentHandlesScope takes over filled blocks from the main thread local handle, remove the block_size_ field and use kHandleBlockSize instead. This way all blocks have exactly the same size.

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.

This is the first step towards implementing a tier-up mechanism from NCI code to TF. We will follow the existing Ignition-to-Turbofan mechanics, which are, roughly: 1. Track a bytecode interrupt budget. 2. When exhausted, call the runtime profiler, which increments profiler ticks for the top frame's function. 3. When a function should tier up, it is marked as such using the FeedbackVector::optimized_code_weak_or_smi slot / the OptimizationMarker mechanism. 4. The InterpreterEntryTrampoline checks this slot and calls into runtime to compile if needed. 5. The finished code is also placed into this slot, as well as installed on the JSFunction. 6. Again, the IET checks the slot and tail-calls the code object if it exists. This CL implements step 1 for NCI code by inserting the new simplified UpdateInterruptBudget operator at the same spots (and using the same offsets) as Ignition. When the budget is exhausted, we call a runtime function that currently does nothing and will be implemented in the next CL.
