Confirmed. I think this is likely to be a bad interaction
between unpacked vectors and the optimisation to use predication
when peeling for alignment. It's really an optimisation/cost model
bug that we used unpacked stores for this testcase at all, but given
that we do, the number of peeled iterations is being calculated
incorrectly.
