InstanceData is the per-instance data for Ruby object. For example, instance variables (@abc), frozen/tainted flags, etc.

We try to be smart about storing it on the object for types that we generate, but if it's a .NET object sometimes we have to go through a dictionary lookup to find the instance data for a given object.
