	(process_switch): If we emit a bit-test cascade, schedule loops
	for fixup.
	* tree-complex.c: Include cfgloop.h.
	(expand_complex_div_wide): Properly add new basic-blocks to loops.
	* asan.c: Include cfgloop.h.
	(create_cond_insert_point): Properly add new basic-blocks to

	(expand_omp_atomic_pipeline): Schedule loops for fixup.
	* tree-ssa-copy.c: Include tree-scalar-evolution.h.
	(fini_copy_prop): Disable DCE in substitute_and_fold if SCEV
	is initialized, not when loops are present.
	* tree-parloops.c (parallelize_loops): Remove checking here.
	* passes.c (init_optimization_passes): Schedule a copy-propagation
	pass before complete unrolling of inner loops.

	* gcc.dg/tree-prof/update-loopch.c: Revert last change.
