    analyzer: fix ICEs treeifying offset_region [PR96646, PR96841]

            * region-model.cc (region_model::get_representative_path_var):
            When handling offset_region, wrap the MEM_REF's first argument in
            an ADDR_EXPR of pointer type, rather than simply using the tree
            for the parent region.  Require the MEM_REF's second argument to
            be an integer constant.
