  Reorganize AST traversal utility code
  
  Define TIntermTraverser and TIntermLValueTrackingTraverser in a
  separate header file. hash() function is moved out from
  TIntermTraverser as it is not related to the core functionality
  of traversing and transforming ASTs.
  
  Also reorganize some traversers to follow common conventions:
  
  - Intermediate output is now in OutputTree.h/.cpp
  - Max tree depth check is now in IsASTDepthBelowLimit.h/.cpp
