	* tree-data-ref.c (have_similar_memory_accesses_1): Remove.
	(ref_base_address_1): Likewise.
	(remove_similar_memory_refs): Likewise.
	* tree-data-ref.h (remove_similar_memory_refs): Remove.
	* tree-loop-distribution.c (classify_partition): Do not classify
	as builtin if -ftree-loop-distribute-patterns is not enabled.
	(fuse_partitions_with_similar_memory_accesses): Inline ...
	(ldist_gen): ... here.  Fuse all non-builtin partitions if
	-ftree-loop-distribution is not enabled.  Properly return
	the number of created partitions.  Do not update SSA form here
	but ...
	(tree_loop_distribution): ... once here for the whole function.
	Only walk innermost loops, constrain loops we consider here
	further.  Do not call remove_similar_memory_refs.
	(distribute_loop): Do not check number of loop nodes here.

	* gcc.dg/tree-ssa/ldist-11.c: Enable -ftree-loop-distribute-patterns.
	* gcc.dg/tree-ssa/ldist-17.c: Likewise.
	* gcc.dg/tree-ssa/ldist-pr45948.c: Likewise.
