    [testsuite] Fix PR94079 by respecting vect_hw_misalign [PR94079]
    
    This is another vect case which requires special handling with
    vect_hw_misalign.  The alignment of the second part requires
    misaligned vector access supports.  This patch is to adjust
    the related guard condition and comments.
    
    Verified it on ppc64-redhat-linux (Power7 BE).

        * gfortran.dg/vect/pr83232.f90: Expect 2 rather than 3 times SLP on
        non-vect_hw_misalign targets.
