Hi,
This patch refactors struct partition for later distribution.  It records
bitmap of data references in struct partition rather than vertices' data in
partition dependence graph.  It simplifies code as well as enables following
rewriting.
Bootstrap and test on x86_64 and AArch64.  Is it OK?

Thanks,
bin

	(partition_alloc, partition_free): Init and release data refs.
	(partition_merge_into): Merge data refs.
	(build_rdg_partition_for_vertex): Collect data refs for partition.
	(distribute_loop): Remve data refs from vertice data of partition
	graph.
