  Store symbol names as a ImmutableString
  
  This will enable compile-time initialization of built-in symbols as
  well as reducing copying strings.
  
  Most of the code that deals with names is changed to use
  ImmutableString where it makes sense to avoid conversions.
  
  The lexer/parser now allocate const char pointers into pool memory
  instead of allocating TStrings. These are then converted to
  ImmutableString upon entering TParseContext.
