Avoid calling verify_ssa twice in verify_loop_closed_ssa. 

2010-04-06  Sebastian Pop  <sebastian.pop@amd.com>

	* graphite-clast-to-gimple.c (graphite_verify): Remove redundant
	call to verify_ssa.  Invoke verify_loop_closed_ssa with an extra
	argument.
	* graphite-scop-detection.c (canonicalize_loop_closed_ssa_form): Same.
	* graphite-sese-to-poly.c (rewrite_reductions_out_of_ssa): Same.
	(rewrite_commutative_reductions_out_of_ssa): Same.
	* passes.c (execute_function_todo): Call verify_ssa for every pass
	in the LNO.  Invoke verify_loop_closed_ssa with an extra argument.
	* tree-flow.h (verify_loop_closed_ssa): Update declaration.
	* tree-parloops.c (parallelize_loops): Invoke verify_loop_closed_ssa
	with an extra argument.
	* tree-ssa-loop-manip.c (check_loop_closed_ssa_stmt): Same.  Call
	verify_ssa only when the extra argument is true.
	(gimple_duplicate_loop_to_header_edge): Invoke verify_loop_closed_ssa
	with an extra argument.
	(tree_transform_and_unroll_loop): Same.
