Original change's description:
> [Memory] Add an OnCriticalMemoryPressure method to V8::Platform.
>
> Adds virtual V8::Platform::OnCriticalMemoryPressure method, default
> implementation does nothing.
>
> Calls this method on first allocation failures in NewArray, Malloced,
> and zone AccountingAllocator and adds retry logic.
>
> Adds utility functions for allocating base::VirtualMemory to functions
> in allocation.h, which call this method and add retry logic.
>
> Calls these utility functions in heap CodeRange, Spaces, StoreBuffer
> and SequentialMarkingDeque.
>
> Bug: v8:6635
