I have either opened new bug reports for these tests, or added links to
existing bugs.
This should help make the lldb-aarch64-ubuntu buildbot green (there will
still be some unexpected passes that someone should look into, but those
can be handled later).
This patch improves the support of DWARF5.
Particularly the reporting of source code locations.
