  Track parameter qualifiers of functions in call nodes
  
  We now add a reference to TFunction to all TIntermAggregate nodes
  where it is possible, including built-in ops. We also make sure
  that internal TFunctions added in traversers have correct parameter
  qualifiers.
  
  This makes TLValueTrackingTraverser much simpler. Instead of storing
  traversed functions or looking up builtin functions from the symbol
  table, determining which function parameters are out parameters can
  now be done simply by looking it up from the function symbol
  associated with the aggregate node.
  
  Symbol instances are no longer deleted when a symbol table level goes
  out of scope, and TFunction destructor no longer clears the
  parameters. They're all either statically allocated or pool allocated,
  so this does not result in leaks.
