STT-tensorflow/tensorflow/lite/kernels/sub_test.cc
Elena Zhelezina 1622cca6dc - Added checks that zero point iz zero for ADD/SUB. 
- POT int16x8: create a new BroadcastSub16POTSlow function to manage the POT scaling.
- General int16x8: the BroadcastAdd4DSlow should be used instead of BroadcastSubSlow as the sign of input2 multiplier is changed in PrepareGeneralSubOp.
