<pre>Fixed by not instrumenting allocas passed to llvm.localescape in r242809.
If we want to find more bugs in code using SEH, we can tweak clang's IRgen to
use more indirection. With ASan, we could escape an alloca that holds pointers
to the other local allocas that we want do UAR and poisoning for.</pre>
