  Simplify parsing struct field declarators
  
  This removes the dummy type that was attached to struct declarators
  while parsing. This makes TParseContext::addStructDeclaratorList in
  particular simpler to understand.
  
  The new TDeclarator data type is the parsed representation of the
  struct_declarator grammar rule. It is completely immutable. The name
  and location stored in TField can also be qualified as constant now.
