Hello.

Hmm. I remember that this was important for performance in some cases on AArch64 - but we don't enable AggressivelyInterleaveReductions. If you have examples of scalar interleaving causing performance problems with AggressivelyInterleaveReductions then it sounds sensible to me to disable it for the if you pointed to as well.
