Oops, sorry, forgot to reply, and also got distracted by a few other things. I ran one bigger benchmark, and didn't see anything worth mentioning. A first preliminary conclusion: looks like we don't miss much by not doing this lowering here. Disclaimer: I've tested only on Arm targets, definitely not on all interesting architecture combinations, and a handful of benchmarks.
