During code generation, we generate self-references (i.e. references to the Code object currently being generated) as references to a temporary handle. When the final Code object has been allocated, the handle's location is fixed up and RelocInfo iteration fixes up all references embedded in the generated code. This adds support for this mechanism to the builtins constants table builder. CodeObject() is now a new handle pointing to a dedicated self-reference marker in order to distinguish between self-references and references to undefined. In Factory::NewCode, we patch up the constants table.
