Synchronous exception-handling (e.g., C++ and Java) is simply
additional (rarely-executed) edges in a control-flow graph,
leaving call sites and throw statements, and targeting handlers.
It helps to expose this as first-class control-flow to your
optimizer and register allocator and scheduler, since you
may discover that you wish to push code down those edges.
