operator GEMM does not compile with template type int

[srohit0]

How to Reproduce

Step 1
Change gemm operator in swig/dnnc.api file to add int shown below:

tensor<output> gemm(tensor<input> &a, tensor<input> &b, 
                                       tensor<input> &c, float alpha = 1.0, float beta = 1.0, 
                                       int transA = 0, int transB = 0) {
     Gemm<output, input, input> op("localOpName", alpha, beta, transA, transB);
     return op.compute(a, b, c);
     dtype = {
         "double" : "double",
         "float" : "float",
         "int" : "int"
     }
}

Step 2

cd swig
make clean
make
