Are we not doing that already? If the nsw flag is set in the LLVM translation, we should be emitting a side-condition about no signed overflow. Maybe that side-condition is wrong.

As far as I can tell, we're doing the correct check here in the event that LLVM emits a lsh with the nsw flag. Unfortunately, it isn't always emitting the flag, even when it would be justified by the source language. As a result, we can't really handle this case unless clang gets more pedantic about the flags it emits.
