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 Trans = 'N' Inc_x = 1 Inc_y = 1 Loops = 1
   SIZE       Flops
 100000 : Segmentation fault (core dumped)
Because j+i*m has exceeded the maximum range of int
