Add VSELECT to LegalizeVectorTypes::ScalariseVectorResult. Previously it would crash if it encountered a 1 element VSELECT. Solution is slightly more complicated than just creating a SELET as we have to mask or sign extend the vector condition if it had different boolean contents from the scalar condition. Fixes <rdar://problem/11178095>
