I wouldn't change replace_phi_edge_with_variable, because even without the duplicate_ssa_name_range_info (say if new_tree already has SSA_NAME_RANGE_INFO) we'd be lying to the compiler. The right thing would be to union the global range of the phi result with the oarg INTEGER_CST, not sure how hard would that be.
