    x86: improve lb_cleanup_memory_ranges
    
    There are 2 issues in lb_cleanup_memory_ranges(). The first
    is that during sort there is a neighbor comparison that initially
    starts with the current entry. The second issue is that merging
    has an off by one comparison for adjacent entries.
