IBM Z: gen-vect-26/28: Vectorizing without peeling is ok for Z

Browse Source 
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.

2019-11-05  Andreas Krebbel  <krebbel@linux.ibm.com>

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