* tree-data-ref.c (stores_from_loop): Remove.
(stmt_with_adjacent_zero_store_dr_p): Likewise.
(stores_zero_from_loop): Likewise.
* tree-data-ref.h (stores_from_loop, stores_zero_from_loop,
stmt_with_adjacent_zero_store_dr_p, stride_of_unit_type_p): Remove.
(adjacent_store_dr_p): New function.
* tree-loop-distribution.c (generate_memset_builtin): Pass
the RDG, use the already available data-reference.
(generate_code_for_partition): Pass down RDG.
(classify_partition): Inline parts of the former
stmt_with_adjacent_zero_store_dr_p here and use adjacent_store_dr_p.
(ldist_gen): Remember if there was any detected builtin and
do less work if not and flag_tree_loop_distribution is not set.
(tree_loop_distribution): Inline and fuse stores_from_loop
and stores_zero_from_loop here.
