vmovups requires AVX, even though we have FMA3 scope, that only enables FMA3 and not AVX. We can't enable AVX when FMA3 is supported (inside of Assembler::Assembler) because we will hit some DCHECKS in SSE instructions that check that AVX is not enabled.

This CL adds an Allocator to SmallVector to control how dynamic storage is managed. The default value uses the plain old C++ std::allocator<T>, i.e. acts like malloc/free. For use with zone memory, one can pass a ZoneAllocator as follows: // Allocates in zone memory. base::SmallVector<int, kInitialSize, ZoneAllocator<int>> xs(ZoneAllocator<int>(zone)); Note: this is a follow-up to crrev.com/c/3240823. Drive-by: hide the internal `reset` function. It doesn't free the dynamic backing store; that's a surprise and should not be exposed to external use.

Internal fields are used for implementing edges to C++ objects in Oilpan. When setting the fields on a JS API object, we should also emit a write barrier for this edge. This mechanism replaces the explicit write barrier in V8's API which is provided through `JSHeapConsistency::*`. The internal barrier should also be slightly faster as it doesn't require any API calls.
