  Refactor CollectVariables
  
  New helper functions are added for collecting built-in variables, and
  the traverser is encapsulated inside VariableInfo.cpp. The helper
  functions get data for built-in variables from the symbol table, so a
  duplicate copy of the data doesn't need to be maintained in
  CollectVariables any more.
