Description

When a CU is IBC mode, weighted pred should not be performed.
However, in VTM7.0rc1, Encoder path for IBC motion compensation goes to normal MC path by calling function xPredInterUni() and xWeightedPredictionUni() when WeightedPredP or WeightedPredB is set to 1.
The function call of xWeightedPredictionUni() should be gated by "if (!CU::isIBC(*pu.cu))"
