Thanks! I think it's also worth adding similar RUN lines to:

Transforms/LoopVectorize/multi_early_exit.ll
Transforms/LoopVectorize/single_early_exit_with_outer_loop.ll (since I've had so many problems with this in the past!)
Transforms/LoopVectorize/single_early_exit_live_outs.ll (even though we don't vectorise at the moment, at least it's defending that deal with live-outs sensibly).
