+ Reverted this commit: as at this point the loop closed SSA form
+ is under a canonical form respecting the single argument condition.
+ * graphite-sese-to-poly.c (scalar_close_phi_node_p): Loop
+ close phi nodes may have more than one argument.

+ * graphite-sese-to-poly.c (rewrite_close_phi_out_of_ssa): Assert that
+ gimple_phi_num_args of the loop close SSA phi node is equal to 1.
+ (detect_commutative_reduction): Same.
