- Moves GetRandomMmapAddr from platform to v8::internal allocation
primitives, in preparation for delegating this to the embedder.
- Adds hint parameters to OS functions that used to use this function.

- Moves base::VirtualMemory to v8::internal::VirtualMemory.
- Makes VirtualMemory platform-independent by moving internals to new
OS:: static methods, for each platform.
This will make it easier to delegate memory management in VirtualMemory
to V8::Platform, so that embedders like Blink can override it. We can't
depend on V8::Platform in base/platform.
