Handle maskReductionCoerced element type in VectorAPIExpansion

[gita-omr]

• maskReductionCoerced intrinsic has element type Int for Float vectors and Long for Double vectors. For the sake of class verification we can leave _elementType field unset and it will be automatically derived from the child type (since they will be in the same class)

@gita-omr I confirmed that the code below gets vectorized with this PR.

       for (int i = 0; i < a.length; i += SPECIES.length()) {
          FloatVector va = FloatVector.fromArray(SPECIES, a, i);
          FloatVector vb = FloatVector.fromArray(SPECIES, b, i);
          VectorMask<Float> vm = va.eq(vb);
          ints[i] = vm.trueCount();
       }
