  Description copied from class: AbstractDOptimizer
  
  An optimizer must implement this method. This method is called by a master optimizer to perform the optimization on the selected target.
  Note that the optimizer is responsible for returning a legal method context, e.g.: the method IR instructions must be consistent with the CFG; the CFG must adhere to certain rules (see cleanGraph); if the data flow analysis is no longer valid, it should be invalidated (see resetDFA); etc.
  
  Specified by:
  
  perform in class AbstractDOptimizer
  
  Returns:
  
  the number of optimizations performed, 0 if none
