Solve the problem of core dumped when using large-scale data in benchmark test 

E.g ：  when running test calse such as below in benchmark:
./dgemv.goto 100000 100000 100000
From : 100000  To : 100000 Step = 100000 Side = L Uplo = U
   SIZE       Flops
 100000 :Segmentation fault (core dumped)
Because i+j*m has exceeded the maximum range of int
