Reduced bc that crashes when passed to `opt`

I had a large test case which ended up crashing in LLVM optimizations when run,
and upon using bugpoint it was simplified down to a small program which will
not crash when passing through `opt` with no flags, but it will crash when
passed through `opt` with the `-jump-threading` flag.

I've attached the bc file to this bug, and just let me know if any more
information is needed!</pre>
