* graphite-sese-to-poly.c (rewrite_close_phi_out_of_ssa): Add back
the case removed in the previous patch, when the only phi argument
is defined in the same loop as the phi node itself. Handle it
separately from the invariant case by both propagating it outside
the region and replacing the phi node with an assign.
