  Split ternary node class from TIntermSelection
  
  Ternary operator nodes are typed parts of expressions, they always
  have two children and the children are also guaranteed to be
  TIntermTyped. "If" selection nodes can't be a part of an expression,
  they can have either one or two children and the children are code
  blocks. Due to all of these differences it makes sense to store these
  using two different AST node classes.
