    More BB vectorization tweaks

    This tweaks the op build from splats to allow loads marked as not
    vectorizable.  It also amends some dump prints with the address of
    the SLP node or the instance to better be able to debug things.

    2020-10-29  Richard Biener  <rguenther@suse.de>

            * tree-vect-slp.c (vect_build_slp_tree_2): Allow splatting
            not vectorizable loads.
            (vect_build_slp_instance): Amend dumping with address.
            (vect_slp_convert_to_external): Likewise.

            * gcc.dg/vect/bb-slp-pr65935.c: Adjust.
