easy_fp_constant accepts const_double, easy_vector_constant accepts
const_vector. Calling one from the other therefore will always return
false. I believe the zero_constant call in easy_vector_constant will
cover the 0.0 case of easy_fp_constant for KFmode and TFmode.
Bootstrapped and regression tested powerpc64le-linux.
* config/rs6000/predicates.md (easy_vector_constant): Don't call
easy_fp_constant.
