Log:
	* tree-ssa-loop-manip.c (split_loop_exit_edge): Return the new block.
	* tree.c (build6_stat): New function.
	* tree.h (build6_stat): Declare.

	Add argument to add_phi_args_after_copy call.
	(tree_duplicate_sese_tail): New function.
	(move_sese_region_to_fn): Update loops.

	* testsuite/gcc.dg/tree-ssa/parallelization-1.c: Update outcome.
