[cfe-dev] david's integer overflow stuff

Hi Chris-

If you mean "can a single trap handler provide both verbose error messages 
and also high-performance interposition like David wants" then I would 
expect that the answer is no.  It takes time and bloats code size to 
marshall up all the arguments that our handler wants.

On the other hand, our interface is basically a superset of David's.  My 
belief is that suporting both trap handling interfaces will not be 
invasive at all, and that it is useful to support both.  The only 
difference is that when compiling a program in verbose trap mode, the 
trap-handling BBs will contain more stuff.
