[PATCH] D67392: [ARM][ParallelDSP] Change smlad insertion order

[Sam Parker via Phabricator via llvm-commits]

Thanks both. I've added a threshold to the number of loads that we can inspect, which causes us to bail before examining any loads. I've also added an early exit into the troublesome loop in RecordMemoryOps.
