* tree-data-ref.h (find_data_references_in_loop): Declare.
* tree-data-ref.c (get_references_in_stmt): Use a stack
vector pre-allocated in the callers.
(find_data_references_in_stmt): Adjust.
(graphite_find_data_references_in_stmt): Likewise.
(create_rdg_vertices): Likewise.
(find_data_references_in_loop): Export.
* tree-vect-data-refs.c (vect_analyze_data_ref_dependences):
Compute dependences here...
(vect_analyze_data_refs): ...not here. When we encounter
a non-vectorizable data reference in basic-block vectorization
truncate the data reference vector. Do not bother to
fixup data-dependence information for gather loads.
* tree-vect-slp.c (vect_slp_analyze_bb_1): Check the number
of data references, as reported.
