      To analyze JDK-8256729 further, we need more tracing:

      1)We should print a mapping of the split area if os::split_reserved_memory fails

      2)The print-mapping code on windows has some shortcomings:
      - does not handle huge areas well (it should be possible to print the whole address space, similar to proc/pid/maps on Linux)
      - Protection information is printed wrong
      - can be printed more concise and maybe adorned with some basic range info, e.g. library mappings
