  Log Message:
  -----------
  Fix the verification of DIEs with DW_AT_ranges.

Summary: Previous code would try to verify DW_AT_ranges and if any ranges would overlap, it would stop attributing any ranges after this to the DIE which caused incorrect errors to be reported that a DIE's address ranges were not contained in the parent DIE's ranges. Added a fix and a test.
