Note, in r236149 I have pulled in a change from upstream clang, which
should fix the root cause of the "failed to retrieve array bounds"
For flexible array members (e.g. arrays at the end of a struct with no
specified size), clang didn't produce correct debug information. This
confused ctfconvert, causing it to bail out.
