These tests check if loop peeling has been applied to avoid
having to vectorize unaligned loops. On Z we do not have any
alignment requirements for vectorization so we also don't need want
the loop peeling here.

* gcc.dg/tree-ssa/gen-vect-26.c: Disable loop peeling check for
IBM Z.
* gcc.dg/tree-ssa/gen-vect-28.c: Likewise.
