Added an Isolate* field to NoTrackDoubleFieldsForSerializerScope, PlatformFeatureScope and BinaryOpIC::State.
The serializer state and even the CPU features will be per-Isolate
later. Currently we get away with global state, because mksnapshot
runs single-threaded and has only 1 Isolate, but this will change.
Furthermore, these changes are yet another prerequisite for removing a
catch-22 at initialization time when we try to enable serialization.
This CL is similar in spirit to r20919, BTW.
