    tree-optimization/109469 - SLP with returns-twice region start

    The following avoids an SLP region starting with a returns-twice
    call where we cannot insert stmts at the head.

            * tree-vect-slp.cc (vect_slp_function): Skip region starts with
            a returns-twice call.

            * gcc.dg/torture/pr109469.c: New testcase.
