While working on improving the jump threading code, I ran into a situation
where we were creating paths where some variables were uninitialized.
I'm not 100% sure the branch bits can trigger this problem. But I wanted
to give everyone a heads-up to the potential problem.
If you're getting an odd/new "... may be uninitialized" warnings, please
let me know. Pass long a .i file and what target you're building for
privately (no need to clog up the list).
I've got a fix that I'll be pondering overnight...
