costmodel-vect-33.c: Expect vectorization to be not profitable if...

        * gcc.dg/vect/costmodel/spu/costmodel-vect-33.c: Expect
        vectorization to be not profitable if peeling is used
        to realign the memory access.
        * gcc.dg/vect/costmodel/spu/costmodel-vect-76a.c:
        Increase loop bound to avoid loop unrolling.
        * gcc.dg/vect/costmodel/spu/costmodel-vect-76c.c:
        Likewise.
