  Don't use TIntermSymbol nodes for function parameters
  
  Parameter nodes are not needed - it's simpler to just create a
  TVariable object for each parameter when the TFunction is initialized.
  
  With this change we also store only one object per each parameter type
  used in built-in functions, instead of one array of TConstParameter
  entries for each unique parameter sequence.
  
  This simplifies code and reduces binary size and compiler memory use.
  Compiler perf does not seem to be significantly affected.
