Message : Guarantee that symbol nodes get unique ids The code is refactored so that symbol nodes can only be initialized with an unique id object. This prevents accidentally forgetting to create an id for a symbol node. This opens up possibilities for future optimization: For example the names and types of symbols could be stored in a central location inside the SymbolTable, and TIntermSymbol nodes would only need to store the symbol id. The symbol id could be used to look up the name and type of the node.
