In some situations it would be useful to just get a pre-symbolicated profile output, for quick testing.
Hopefully this will become moot when we can symbolicate after the fact, but in the meantime I think it will be a small but useful feature. (Especially for selfish me, who wants to see some quick results while working on the non-libxul profiler!)
Note that this will be an option set in an environment variable, so it won't impact "normal" users -- apart from an initial check of that env-var.

As per the help message, this can create significant pauses and prevents
future (better) symbolication, but it can be useful to developers for local
tests.

Also note that this is using mozilla/StackWalk.cpp's MozDescribeCodeAddress(), which doesn't seem to be able to symbolicate Firefox on Linux, so don't expect miracles! It works fine on Windows though.
