Ah ha!  After some pretty intense studying, looks like libunwind gives
enough information for us to distinguosh which thrown objects should
be stringed together.

All what I think is needed is for gdc to emit some __begin_catch call
which builds and returns the constructed Exception object to be passed
to user-land.
