After this commit:
`std.debug.SelfInfo` is a cross-platform abstraction for the current
executable's own debug information, with a goal of minimal code bloat
and compilation speed penalty.
`std.debug.Dwarf` does not assume the current executable is itself the
thing being debugged, however, it does assume the debug info has the
same CPU architecture and OS as the current executable. It is planned to
remove this limitation.
std.debug.Dwarf is the parsing/decoding logic. std.dwarf remains the
unopinionated types and bits alone.
If you look at this diff you can see a lot less redundancy in
namespaces.
