    xfail store_merging_19.c for the same reason as store_merging_18.c
    
    store_merging_19.c is almost the same as store_merging_18.c except
    it has assume align in it to allow it work on strict align targets.
    Somehow when I was looking at the testresults I noticed 18 but not 19
    when I was looking into failures.
    
    Pushed as obvious.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/store_merging_19.c: xfail.
