The main issue was that some valid length values were wrongly interpreted as reserved, which come from inconsistency in the DWARF3 documentation which was fixed in DWARF4. See D64622 <https://reviews.llvm.org/D64622> and http://lists.dwarfstd.org/pipermail/dwarf-discuss-dwarfstd.org/2008-June/003343.html for more details.

I have created D72695 <https://reviews.llvm.org/D72695> for the test.
