Refactor BB splitting of DRs for SLP group analysis
This uses the group_id computed to ensure DRs in different BBs do
not get merged into a DR group. To achieve this we seed the
group from the BB index when group_ids are not computed and we
make sure to bump the group_id when advancing to the next BB for
BB SLP analysis.
This paves the way for relaxing the grouping for BB vectorization
by adjusting its group_id computation.

* tree-vect-data-refs.c (dr_group_sort_cmp): Do not compare
BBs.
(vect_analyze_data_ref_accesses): Likewise. Assign the BB
index as group_id when dataref_groups were not computed.
* tree-vect-slp.c (vect_slp_bbs): Bump current_group when
we advace to the next BB.
