  Refactoring: Make creating temporary symbols in AST traversal reusable
  
  Temporary symbols will also be needed to store temporary arrays when complex
  array expressions are unfolded.
  
  Also clear tree update related structures at the end of updateTree(), so that
  the traverser can be reused for several rounds of replacement more easily, and
  remove unnecessary InVisit step from UnfoldShortCircuitToIf.
