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