This means we only collect reliability information in the case
where we're specifically doing a reliable stacktrace. For
example when printing stack traces on the console it might be
useful to print a ? or something if the frame is unreliable as a
hint to the reader that the information might be misleading.
Could we therefore change the flag here to a reliability one and
our need_reliable check so that we always run
unwind_is_reliable()?
I'm not sure if we need to abandon the trace on first error when
doing a reliable trace but I can see it's a bit safer so perhaps
better to do so. If we don't abandon then we don't require the
need_reliable check at all.
