[PATCH test]Refine test string for scev-8.c

[Bin Cheng]

Hi,
Dump information of IVOPT has been improved, while scanning string in 
gcc.dg/tree-ssa/scev-8.c was left over because it appears as PASS.  This patch 
changes test string to what should be tested.
Test result checked.  This is an obvious change.

Thanks,
bin
