[Bernhard Reutner-Fischer via Gcc-patches]

From: Bernhard Reutner-Fischer <al...@gcc.gnu.org>

gcc/analyzer/ChangeLog:

        * region-model-manager.cc (get_code_for_cast): Use _P defines from
        tree.h.
        (region_model_manager::get_or_create_cast): Ditto.
        (region_model_manager::get_region_for_global): Ditto.
        * region-model.cc (region_model::get_lvalue_1): Ditto.
        * region.cc (decl_region::maybe_get_constant_value): Ditto.
