Arrgh.  Exception handling uses invoke and doesn't use unwind!  Or did
I just miss it?

Since unwind doesn't take any operands, is there *any* possible
implementation of unwind that fits with exception handling/invoke?

Implemented as an optional pass, my scheme can go unused when you're
using the g++ front-end or something else that uses __cxa_throw.
