    testsuite/vect: Make match patterns more accurate.
    
    On some targets we fail to vectorize with the first type the vectorizer
    tries but succeed with the second.  This patch changes several regex
    patterns to reflect that behavior.
    
    Before we would look for a single occurrence of e.g.
    "vect_recog_dot_prod_pattern" but would possible have two (one for each
    attempted mode).  The new pattern tries to match sequences where we
    first have a "vect_recog_dot_prod_pattern" and a "succeeded" afterwards
    while making sure there is no "failed" or "Re-trying" in between.
    
    gcc/testsuite/ChangeLog:
    
            * gcc.dg/vect/vect-outer-4c-big-array.c: Adjust regex pattern.
            * gcc.dg/vect/vect-reduc-dot-s16a.c: Ditto.
