  public PcodeEmit(ParserWalker walk, InstructionContext ictx, int fallOffset, PcodeOverride override)
  
  Pcode emitter constructor
  
  Parameters:
  
  walk - is the ParserWalker state for the tree that needs to be walked to generate pcode
  
  ictx - is the InstructionContext interface to resolve requests for context
  
  fallOffset - default instruction fall offset (i.e., instruction length including delay slotted instructions)
  
  override - required if pcode overrides are to be utilized
