It adds the mask information to the original intrinsic methods which are called both by masked and non-masked unary/ternary operations. For non-masked operations, the mask class and value are set to null.

@PaulSandoz  @iwanowww , I'v rename all the masked op back to the original names. Could you please help to look at again? Waiting for your feedback, Thanks so much!
