    [torque] Generate GC object visitors for Torque classes · 4f4d73f2

    In the process:
    
    * Augment C++-generated Torque classes with SizeFor methods to
      calculate size of instances.
    
    * Add a new "@generateBodyDescriptor" annotation that causes Torque to
      generate C++ BodyDescriptors code that can be used to visit objects
      compatible with existing V8 mechanisms, e.g. GC
    
    * Fully automate C++ macro machinery so that adding non-extern Torque
      class doesn't require any C++ changes, including ensuring generation
      of instance types and proper boilerplate for validators and
      printers.
    
    * Make handling of @export a true annotation, allowing the modifier to
      be used on class declarations.
    
    * Add functionality such that classes with the @export annotation are
      available to be used from C++. Field accessors for exported classes
      are public and factory methods are generated to create instances of
      the objects from C++.
    
    * Change the Torque compiler such that Non-exported classes implicitly
      have the @generateBodyDescriptor annotation added and causes both
      verifiers and printers to be generated.
    
    * Switch non-extern Torque classes from using existing Struct-based
      machinery to being first-class classes that support more existing
      Torque class features.
