Hi,
This patch computes and returns separate aff_trees for invariant expression
and induction expression, so that invariant and induction parts can be handled
separately in both cost computation and code generation.

Is it OK?

Thanks,
bin

	* tree-ssa-loop-ivopts.c (get_computation_aff_1): New.
	(get_computation_aff): Reorder parameters.  Use get_computation_aff_1.
	(get_computation_at, rewrite_use_address): Update use of
	get_computation_aff.
