I believe the DWARFv5 support is complete now with my last 2 commits
when not combined with --odr.

There are still failures with the ODR support when building the
testcases with -gdwarf-5, specifically:

FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-class-ns.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-def-decl.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-loc.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-struct.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-struct-ns.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-union.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-class.sh
FAIL: /opt/local/src/dwz/testsuite/dwz.tests/odr-union-ns.sh

It looks like ODR detection simply doesn't work with DWARF5, so no size
reduction is produced. I haven't figured out why yet.

That said, it would be nice to see a new release. We can always say
that ODR support is experimental and doesn't yet work for DWARF5.

Cheers,
