    PR29785, memory bloat after b43771b045fb

    Pathological cases of dwarf info with overlapping duplicate memory
    ranges can cause splitting of trie leaf nodes, which in the worst case
    will cause memory to increase without bounds.

            PR 29785
            * dwarf2.c (insert_arange_in_trie): Don't split leaf nodes
            unless that reduces number of elements in at least one node.
