    tree-optimization/115867 - ICE with simdcall vectorization in masked loop

    When only a loop mask is to be supplied for the inbranch arg to a
    simd function we fail to handle integer mode masks correctly.  We
    need to guess the number of elements represented by it.  This assumes
    that excess arguments are all for masks, I wasn't able to create
    a simdclone with more than one integer mode mask argument.

    The gcc.dg/vect/vect-simd-clone-20.c exercises this with -mavx512vl

            PR tree-optimization/115867
            * tree-vect-stmts.cc (vectorizable_simd_clone_call): Properly
            guess the number of mask elements for integer mode masks.
