    tree-optimization/110221 - SLP and loop mask/len

    The following fixes the issue that when SLP stmts are internal defs
    but appear invariant because they end up only using invariant defs
    then they get scheduled outside of the loop.  This nice optimization
    breaks down when loop masks or lens are applied since those are not
    explicitly tracked as dependences.  The following makes sure to never
    schedule internal defs outside of the vectorized loop when the
    loop uses masks/lens.

            * tree-vect-slp.cc (vect_schedule_slp_node): When loop
            masking / len is applied make sure to not schedule
            intenal defs outside of the loop.

            * gfortran.dg/pr110221.f: New testcase.
