Changed Class * to Class in order to match NEXTSTEP and OpenStep runtime.

Changed Class * to Class in order to match NEXTSTEP and OpenStep
runtime.
(objc_static_instances): New struct to record static instances of a certain
class.
(objc_module): New tag STATICS to point to the table of objc_statics_instances.
