[PATCH test]Revise gcc.dg/vect/pr57558-1.c by using int instead of long

[Bin Cheng]

Hi,
Case gcc.dg/vect/pr57558-1.c uses unsigned long at the moment which can't be 
vectorized on Sparc64.  This patch revises it by using unsigned int.  I think 
it's an obvious change.
Test result checked, is it OK?

Thanks,
bin
