When object support was first added to HHVM, a class named "Instance" was introduced (deriving from ObjectData) to represent instances of user defined classes. Since then, things have evolved and HPHPc and HPHPi have been retired, and now there really is no needed to have ObjectData and Instance be separate classes anymore. This diff moves all of the functionality from the Instance class to the ObjectData and removes the Instance class. In the process, I got rid of a bunch of dead methods and fixed some indentation and other style issues.
