    tree-optimization/109219 - avoid looking at STMT_SLP_TYPE

    The following avoids looking at STMT_SLP_TYPE apart from the only
    place needing it - transform and analysis of non-SLP loop stmts.
    In particular it doesn't have a reliable meaning on SLP representatives
    which are also passed as stmt_vinfo to vectorizable_* routines.  The
    proper way to check in those is to look for the slp_node argument
    instead.

            PR tree-optimization/109219
            * tree-vect-loop.cc (vectorizable_reduction): Check
            slp_node, not STMT_SLP_TYPE.
            * tree-vect-stmts.cc (vectorizable_condition): Likewise.
            * tree-vect-slp.cc (vect_slp_analyze_node_operations_1):
            Remove assertion on STMT_SLP_TYPE.

            * gcc.dg/torture/pr109219.c: New testcase.=
