[Runtime] Improved symbolication option for backtracing.
...
Rather than just on or off, I've changed it to allow "off", "fast",
or "full". "fast" means that we'll do symbol lookup, but we won't
try to find inline frames and we won't run line number programs
(those are the things that are taking considerable time in some
cases).

[Backtracing] Add an option to output to stderr.
...
In CI, it would be better if the backtraces went to stderr rather than
stdout, so provide an option for that.

[Backtracing] Add control over symbol caching.
...
Some symbolication frameworks have a symbol cache; we probably don't want
to use that for test cases, to avoid running into problems where the cache
holds stale information.
