- DWARF v5 has a slightly different header; this recognizes it so we don't fail immediately
- Add support for the line_strp form
- Allow for a graceful failure if a debug abbreviation is missing; I've only seen this when compiling for TSAN, and I'm honestly not entirely sure if this is a bug in the DWARF generation for those tools vs a subtle flaw in our parsing, but bailing out early and skipping introspection seems kinder than assert-fail.
