Subject: [PATCH] Solve the problem of core dumped when using large-scale data
 in benchmark test

 ./ssymv.goto 100000 100000 100000
From : 100000  To : 100000 Step = 100000 Uplo = 'L' Inc_x = 1 Inc_y = 1 Loops = 1
   SIZE       Flops
 100000x100000 : Segmentation fault (core dumped)
Because i+j*m has exceeded the maximum range of int
