	* graphite-isl-ast-to-gimple.c
	(translate_isl_ast_to_gimple::get_rename_from_scev): Remove unused
	parameters and dominance check.
	(translate_isl_ast_to_gimple::graphite_copy_stmts_from_block): Adjust.
	(translate_isl_ast_to_gimple::copy_bb_and_scalar_dependences): Likewise.
	(translate_isl_ast_to_gimple::graphite_regenerate_ast_isl):
	Do not update SSA form here or do intermediate IL verification.
	* graphite.c: Include tree-ssa.h and tree-into-ssa.h.
	(graphite_initialize): Remove check on the number of loops in
	the function and inline into graphite_transform_loops.
	(graphite_finalize): Inline into graphite_transform_loops.
	(graphite_transform_loops): Perform SSA update and IL verification
	here.
	* params.def (PARAM_GRAPHITE_MIN_LOOPS_PER_FUNCTION): Remove.

	* gcc.dg/graphite/pr35356-3.c: XFAIL again.
	* gcc.dg/graphite/pr81373-2.c: Copy from gcc.dg/graphite/pr81373.c
	with alternate flags.
