JDK-8325155 - C2 SuperWord: remove alignment boundaries
Description
Move assigning it out from SuperWord::find_adjacent_refs. Either assign it in SuperWord::filter_packs_for_alignment, or else find it directly in SuperWord::adjust_pre_loop_limit_to_align_main_loop_vectors.

We can also use the aw of the vector directly, rather than the possibly larger vector_width_in_bytes of the type.
