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.
