	* omp-low.c (pass_data_expand_omp): Set properties_provided to
	PROP_gimple_eomp.
	(pass_expand_omp::gate): Remove function.  Move gate expression to ...
	(pass_expand_omp::execute): ... here, as new variable gate.  Add early
	exit if gate is false.
	(pass_data pass_data_expand_omp_ssa): New pass_data.
	(class pass_expand_omp_ssa): New pass.
	(make_pass_expand_omp_ssa): New function.
	* passes.def (pass_parallelize_loops): Use PUSH_INSERT_PASSES_WITHIN
	instead of NEXT_PASS.
	(pass_expand_omp_ssa): Add after pass_parallelize_loops.
	* tree-parloops.c (gen_parallel_loop): Remove call to omp_expand_local.
	(pass_parallelize_loops::execute): Don't do cleanups TODO_cleanup_cfg
	and TODO_rebuild_alias yet.  Add TODO_update_ssa.  Set
