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.
