+ /// getValueType - Return an ID for the concrete type of this object. This is
+ /// used to implement the classof checks. This should not be used for any
+ /// other purpose, as the values may change as LLVM evolves. Also, note that
+ /// for instructions, the Instruction's opcode is added to InstructionVal. So
+ /// this means three things:
+ /// # there is no value with code InstructionVal (no opcode==0).
+ /// # there are more possible values for the value type than in ValueTy enum.
+ /// # the InstructionVal enumerator must be the highest valued enumerator in
+ /// the ValueTy enum.
