streamlined class init, which was a mixed case of registerClass()/initializeClass() and pushRequiredClinits(). Now it is a single initializeClass(ti) method which combines the previous initializeClass(), pushRequiredClinits() and pushClinit() methods. The reason for combining these is the forthcoming replacement of separately locked clinits from different DirectCallStackFrames with a single synthetic frame that calls clinits from nested synchronized blocks. This is required to model hotspot, which does cause deadlocks with concurrent init of classes that cause subclass init during their clinit executions.
