They already work.  [Yes, I was.]

I saw the eh stack, the code can be cleaned up and merged.  For now,  
I'm just cleaning up stack depth stuff, but, yes, logically, all these  
things go together, and half goes into sema, half in codegen.  Also,  
I've not seen the code for cleanup actions, but, it logically goes  
with this stuff as well.  Are we just missing a ton of it, or is it  
hiding somewhere?  If you want to pull the stack depth code into a  
merged nicely designed solution, that'd be great.   I'm still  
sweeping, but I'm close to basic functionality.
