    tree-optimization/114231 - use patterns for BB SLP discovery root stmts

    The following makes sure to use recognized patterns when vectorizing
    roots during BB SLP discovery.  We need to apply those late since
    during root discovery we've not yet done pattern recognition.
    All parts of the vectorizer assume patterns get used, for the testcase
    we mix this up when doing live lane computation.

            PR tree-optimization/114231
            * tree-vect-slp.cc (vect_analyze_slp): Lookup patterns when
            processing a BB SLP root.

            * gcc.dg/vect/pr114231.c: New testcase.
