    adjust iteration count for ppc costmodel 76b
    
    The original intention of this case is to expect not profitable for
    peeling.  Tweak the loop bound to make this loop not profitable to be
    vectorized for !vect_no_align with peeling (both pwr7 and pwr6) and
    keep consistent.
    
    
    for  gcc/testsuite/ChangeLog
    
            * gcc.dg/vect/costmodel/ppc/costmodel-vect-76b.c (N): Tweak.
