    Fix static array size in gcc.dg/vect/vect-simd-20.c
    
    10000 / 78 is strictly greater than 128 so we will
    actually do 128+1 strides in foo() for s == 78 and p[]
    needs to be dimensioned accordingly.

            * gcc.dg/vect/vect-simd-20.c: Fix size of p[]
            to accommodate the number of strides performed
            by foo() for s == 78.
