	labels if the immediate dominator is also the only predecessor. * tree-ssa-dom.c (record_equivalences_from_incoming_edge): Only look at case labels if the immediate dominator is also the only predecessor. Don't look for more case labels if the first seen is a case range. From-SVN: r82480

	* toplev.h (flag_delete_null_pointer_checks): Move from here to... * flags.h (flag_delete_null_pointer_checks): Here. * tree-flow.h (cprop_into_successor_phis): Add argument to prototype. * tree-phinodes.c (resize_phi_node): Initialize PHI_ARG_NONZERO. (add_phi_arg, remove_phi_arg_num): Similarly. * tree-ssa-copy.c (cprop_into_successor_phis): Propagate nonzero property into PHI nodes. * tree-ssa-dom.c: Remove redundant inclusion of flags.h. (record_equivalences_from_phis): If all PHI arguments are known to be nonzero, then the result must be nonzero as well. (cprop_into_phis): Pass nonzero_vars bitmap to cprop_into_successor_phis (record_equivalences_from_stmt): Check flag_delete_null_pointer_checks appropriately. Walk the USE-DEF chains and propagate nonzero property as appropriate. * tree.h (PHI_ARG_NONZERO): Define. (phi_arg_d): Add nonzero flag. From-SVN: r81968

	marking bypassed virtuals for out-of-ssa. * tree-ssa-dom.c (redirect_edges_and_update_ssa_graph): Don't even bother marking bypassed virtuals for out-of-ssa. Instead merge bypassed virtuals into vars_to_rename just before into-ssa pass. From-SVN: r81872
