Re: New stack trace code

We need a way to disable line number info, even when we have our own
built-in dwarf reader.

Something like this, perhaps.

Try -Dgnu.gcj.runtime.NameFinder.use_addr2line=false

addr2line is certainly too slow when an application calls it frequently, but I think maybe we should wait until we do some performance tests on the dwarf2 reader before deciding whether it is neccessary for an option that disables line numbers globally. Also, the overhead of getting line numbers for interpreted frames is small, so I don't think it makes sense to disable for that case as well.
